Zhu Yunwen understood very well that the Ming Dynasty could only be self-sufficient in a limited way. The lives of the people of the Ming Dynasty had improved significantly, and they had accumulated a considerable amount of money.

In this situation, they have formed a virtuous cycle society, which is constantly progressing and the lives of the people are constantly improving.

This has become a pattern that can continue to develop steadily.

But Zhu Yunwen believed that this was not enough, because he also wanted the people of the Ming Dynasty to live happier lives, which inevitably led to the mention of a word: foreign trade.

As we all know, when the economy develops rapidly and a certain place becomes saturated, it is necessary to bring in wealth from outside.

This can be understood as foreign trade.

In the future that Zhu Yunwen knew, every country attached great importance to foreign trade. If foreign trade could be done well, the country would become richer and the people would become richer.

Only in this way can we achieve sustained economic growth.

Therefore, Zhu Yunwen's purpose in bringing these princes and princesses to visit the Ming Dynasty was quite obvious.

No amount of words can change anything; let them see for themselves.

Zhu Yunwen knew that whether it was selling products or anything else, customers had to see them in person before he would be interested; saying more would be useless.

This is why the success rate increases exponentially once a salesperson brings a customer to the store to see the product.

Having only just entered the Ming Dynasty, and within this county town in Guanzhong, the princes and princesses were already captivated by all things Ming Dynasty and unable to extricate themselves.

They not only saw the sturdy, flat, and clean cement road, but also the bicycles and tricycles that were very popular in the Ming Dynasty, as well as various small human-powered vehicles used to transport goods.

These things broadened their horizons, especially the fact that the common people not only did not have any stench, but also had a pleasant fragrance.

This made the princesses even more curious, so after some questioning, all the princesses and princes spent money to buy the floral water.

Meanwhile, some princes and princesses also began to learn about the various delicacies of the Ming Dynasty.

They discovered that the Ming Dynasty was incredibly rich in resources, with an endless variety of foods that completely overturned the princes and princesses' usual concepts of food and gourmet cuisine.

If the seeds of these foods were imported into their country in large quantities, it would certainly add a lot of fun to the people of that country.

Another point is that a princess caught a cold while traveling and the accompanying doctor treated her for a day or two, but it didn't help much.

So he decided to find a doctor in the county town to take a good look at him. Only then did he realize that there was actually an official medical clinic built by the imperial court in the county town.

Medical care is very cheap.

Moreover, the doctors there have extremely high medical skills.

So the princess was taken to the clinic. Upon entering, she discovered that there were indeed many people there seeking medical treatment.

The doctors also had a clear division of labor; those with medical skills would sit in on consultations and be responsible for treating patients.

Some of the women were responsible for receiving patients in the clinic, taking them to fill out basic information, get a number, and see a doctor who specialized in that type of illness based on their symptoms.

They would also get the medicine for the patients and even provide the service of decocting the medicine.

The clear division of labor among these doctors and staff not only greatly improves efficiency but also makes it very convenient for those seeking medical treatment.

Such medical conditions and services greatly surprised the princess who was seeking treatment.

This is unthinkable in their country; it's extremely difficult for ordinary people to see a doctor, and the doctors' skills are not very good.

However, even in this small county town of the Ming Dynasty, there was a dedicated official clinic where treatment was very cheap, forming a welfare system.

After the princess took the medicine prescribed by the doctor, she quickly felt its effects, which made her admire how advanced and powerful the medical conditions in the Ming Dynasty were.

In the small county town of the Ming Dynasty, princes and princesses from various countries learned about the power of the Ming Dynasty from different perspectives, and also came to know the Ming Dynasty as it was today from different angles.

This made them sigh in their hearts, realizing that a place like the Ming Dynasty was truly a place where people could live.

Comparing them to their country is like comparing heaven and hell.

This made the princes and princesses feel very ashamed, and at the same time, they made up their minds to study hard and learn the good things of the Ming Dynasty to bring back to their country.

Furthermore, we should establish a deep cooperation with the Ming Dynasty, and even if there are areas where we lag behind, we should not exaggerate the situation.

After resting briefly in Guanzhong County, the group continued their journey, led by Zhu Yunwen, towards Nanjing, the capital of the Ming Dynasty.

After the initial shock, along the way, although everyone was somewhat prepared, they were still awestruck by what they saw in many places.

For example, the cement roads that connected almost all parts of the Ming Dynasty, and the tourists traveling to various places by bicycle or tricycle.

Every time they stop to rest in a new place, these princes and princesses get to see the local specialties again, and they also get to witness the development of that place once more.

And the happy life of the people.

Such a shock will always exist, no matter how many times it happens.

This alone shows just how much surprise and disbelief the Ming Dynasty brought them.

In this way, although everyone moved very slowly, and often stopped to rest after arriving at certain places.

However, because the road was so good, it only took three or four days to travel from the border of the Ming Dynasty to Nanjing.

Upon arriving in Nanjing, the princes and princesses were once again speechless with astonishment at the sheer size of the city.

Before this, they never imagined that the capital of a country could be so large.

The key point is that the various buildings in this imperial city are also very beautiful, including antique wooden buildings and magnificent brick buildings.

Most importantly, these people are now starting to use cement to build houses.

Bricks are already in use, and brick houses built with bricks and cement are even more stable.

So it has become a trend, leading many wealthy people in Beijing to demolish their old wooden buildings and build more sturdy houses with bricks and cement.

Therefore, the capital city has all kinds of buildings, which dazzled the princes and princesses.

Such a vast imperial city, such a massive city, was something that the princes and princesses of these small countries could never even dream of.
