Chapter 120 How did you get into Xuyuan? (asking for monthly votes)
In April, Lashou.com held two group buying sales events on FoxTao, with cumulative sales reaching 57 million and an increase of 230,000 new customers.
Lashou.com paid 20 million in marketing fees and 9.2 million in new customer acquisition rewards for this, but the return on investment was barely 2, which seems not worth it.
However, this sales volume of 57 million allowed Lashou to increase its market share by 3.5% in the industry competition in April, firmly suppressing Meituan, Wowotuan and Gaopeng.com.
Even Juhuasuan, which has tens of millions of daily active users, failed to surpass Lashou.com in its first month after entering the group buying market.
At first, Chen Yansen was paying attention to the competition in the group buying industry, but later he was busy preparing for the super sale day on April 22 and stopped paying attention to it.
With the joint efforts of the distribution team, event team and operation team, at the end of the three-day event, FoxTao's daily active users exceeded 3 million for the first time.
But Chen Yansen knew that based on the current weekly retention rate, it would be good if the daily active users could stabilize at 2.7 million by the end of the month.
At the end of the event, the total sales volume was 93 million, but it was announced to the public as 100 million.
The gross profit margin dropped from 10% to 6.3%. Excluding the cost of purchasing volume by the delivery team, the revenue from this event was almost zero.
Fortunately, the fame has spread!
After more than half a year of market cultivation and user education, many potential users no longer regard shopping guide e-commerce as a scam website even if they have never used FoxTao.
Chen Yansen put down the "Introduction to Algorithms" and "C Primer Plus" in his hands, stood up and walked downstairs.
I am still thinking about how to solve the problem of Android system lag.
In fact, Android system lags are not entirely due to software issues; hardware problems also limit smoothness.
The mobile phone processors in 2011 had low main frequency and few cores, making it difficult to complete calculations quickly, resulting in slow operation.
Moreover, the running memory of Android phones at that time was generally between 512MB and 1GB, and the body storage was mostly 4GB or 8GB. The reading and writing speeds were slow, and lags were inevitable.
Chen Yansen was powerless to change the hardware, but at the system level, he wanted to develop a more efficient memory management algorithm to solve the shortcomings of memory usage and fragmentation.
Currently, he has two ideas for this problem. One is to optimize the process scheduling algorithm to improve the system response speed; the other is to adopt a generational garbage collection algorithm, adjust the triggering conditions and strategies of garbage collection, and improve the recycling efficiency.
Chen Yansen organized his thoughts, walked to the office area of the Aurora R&D team, and called Wang Teng out.
"Brother Sen, the preliminary architecture of Aurora has been designed. There are three versions of the interface prototype. The system startup and file system modules have just passed the test..."
Wang Teng thought Chen Yansen came to ask about the development progress, so he took the initiative to report.
"I'm not here to hear this from you. Do you have any good suggestions for the problems of system freezes and slow phone speeds?"
Chen Yansen waved his hand, found a temporary meeting room, and the two sat down to talk.
"The usual approach is to reduce animation effects, lower screen resolution, and sacrifice some user experience, or start with hardware, increase memory, or use a more powerful multi-core processor."
Wang Teng frowned and replied seriously based on his experience at OPPO.
“Is there a better way at the system level?”
Chen Yansen shrugged. He didn't want to sacrifice user experience, nor did he intend to use low-end processors to perfunctorily deal with users.
"Improve the memory management mechanism or optimize process scheduling, but OPPO and other domestic mobile phone manufacturers have tried it, and the effect is not very good."
Wang Teng spoke as he thought, while pointing out the drawbacks of these two methods.
More than a decade later, Android phones can be used for three or four years without any lags. On the one hand, this is because Google has continuously upgraded its operating system and solved the defects of the initial version.
On the other hand, hardware has developed by leaps and bounds, and 16GB+1TB storage combinations have become the norm, so there is naturally no worry about lag.
"I have an idea to divide the data into the new generation, the old generation and the metaspace, create different memory areas, and help users clean up garbage data in real time in the background based on information such as garbage collection time, frequency, and memory usage, combined with intelligent algorithms..."
After listening to what Wang Teng said, Chen Yansen knew that current mobile phone manufacturers have no good solution to the problem of system lag.
He paused for a moment, then spoke slowly, explaining his ideas and how to implement the code.
As Wang Teng listened, his pupils gradually dilated and his face was filled with shock.
He remembered that more than 20 days ago, Chen Yansen didn't know much about programming and algorithms, and had asked him to recommend relevant books.
In less than a month, the other party has reached a professional level from zero foundation, has clear ideas, and can even provide reliable solutions from a technical perspective.
Wang Teng's heart was in turmoil. He really wanted to ask Chen Yansen how he got into Xucheng College? With this learning ability, not to mention Peking University and Tsinghua University, the top 985 universities in China, wouldn't Chen Yansen be able to choose? "Hmm? Did you remember it clearly?"
Seeing that Wang Teng was distracted, Chen Yansen raised his voice and asked.
"I'm listening, Brother Sen, please continue." Wang Teng came back to his senses and responded quickly.
"In short, what I want is not a copy of OPPO's Unique UI, but a brand new customized UI."
Chen Yansen patted Wang Teng on the shoulder and gave him gentle instructions.
"Okay, Brother Sen, I will follow your idea and communicate with the developers to implement the generational garbage collection algorithm as soon as possible."
Wang Teng thought about it and felt that Chen Yansen’s plan was feasible, so he promised seriously.
"Okay, get back to work."
After Chen Yansen finished speaking, he turned back to the second floor, picked up the book, and walked towards the library.
Recently, Chen Yansen often hangs out in the library. In addition to reading books on computer and software engineering, he also occasionally flips through French vocabulary books.
With the experience of learning English, he found that he could master a new language in 7 days.
In the first two days, focus on learning vocabulary, grammatical structure, parts of speech and sentence patterns; on the third and fourth days, watch ten movies with original soundtracks; on the fifth and sixth days, integrate what you have learned and make adjustments in pronunciation, intonation and expression through deliberate practice. On the seventh day, you will basically be able to speak fluent English or French.
Africa is the third largest market for smartphones, with 70% of adults under the age of 30. Their demand and curiosity for digital products are no less than those in Southeast Asia.
Chen Yansen would certainly not miss such a big market. Learning French in advance is also a preparation for market expansion.
After all, there are nearly 200 million people in this land who use French as their official language.
Chen Yansen took the book he had just borrowed and went to the reading room upstairs, reading it attentively.
If Chen Guobin saw this scene, he would probably be shocked, because Chen Yansen had never put much effort into studying since he was a child.
"Buzz buzz buzz——" the cell phone vibrates.
Chen Yansen took out his phone and pressed the answer button. Before he could say anything, he heard Liao Wei say on the other end of the phone: "Mr. Chen, the warehouse in Lighthouse Country has been settled, and the staff is in place. When will the overseas shopping assistance function on FoxTao be launched?"
"You can do it anytime, but don't let anything go wrong this time." Chen Yansen smiled, his tone relaxed but with a warning.
"Don't worry, I'll keep an eye on it myself." Liao Wei understood what Chen Yansen was worried about and quickly made his assurance.
The last fake liquor scandal caused Yunsu Express’ business volume to plummet.
Even though Chen Yansen stepped in, Jiushen.com still terminated its exclusive cooperation with Yunsu and instead chose another express company.
Liao Wei knew clearly that if he failed to satisfy Chen Yansen this time, he would most likely have to struggle with Yunsu.
If someone gives you an opportunity, you have to seize it! "Okay, you pull the person in charge of order docking into the project group and launch it as soon as possible."
Chen Yansen said readily.
It has been almost two months since he proposed the idea of an overseas transit warehouse, which is indeed a bit long.
However, he also knew that Liao Wei was very capable in being able to successfully rent a large overseas warehouse and recruit staff, and someone else might not be able to do the same.
Chen Yansen took the phone, walked to the corridor outside the window, and called Zhuang Rui, asking him to put the overseas shopping transit function that had been developed in advance online.
"Okay, Brother Sen." After receiving the instruction, Zhuang Rui immediately followed the instruction and first circled 20% of the users for testing to observe the conversion effect of the new function.
This will determine whether to continue cutting the full amount.
Fox Taobao has nearly 3 million daily active users. It is too risky to launch new features directly, so AB testing or unit testing is generally used to reduce the losses caused by potential bugs.
