According to the old imperial custom, Lin Hai had to visit the homes of ordinary people.

It's a pity that there are not many wealthy families in Qinghe, and most of the people's houses are still cramped and dilapidated old houses. Although entering Lin Hai is not a problem, if so many guards rush in together, the only outcome will be that the houses will be crushed and the Earl of Qinghe will be buried alive.

Therefore, according to the prior requirements, families and businesses that needed to receive Qinghe Bo moved the meals for the reception and the gifts for display to the street.

Of course, not every family has such an honor.

The families that can host Lin Hai are those who have gone through multiple rounds of screening by the Ministry of the Interior. Under the premise of ensuring safety, they include families of martyrs, model soldiers supporting the army, model workers, model researchers, model educators...

Even Lin Hai couldn't remember that he had ever approved so many models.

But considering that the whole family, from the youngest to the breastfeeding child to the oldest... well, not that far, the Qinghe society, which is basically composed of refugees, is still far from an aging population. After all, older people will not live to see the day when they are saved by the Qinghe River.

Lin Hai first walked along the street, visiting each house and accepting greetings from each host. He asked about their lives, whether they were short of food and clothing, and whether they had been treated unfairly. After receiving positive answers, Lin Hai would pick up the wine glass and drink the water that had been tested dozens of times in public. Then he took the chopsticks from Shi Zhen'er and took a bite of the half-eaten meal that had been torn into pieces by his brother-in-law and the guards.

Because it was winter and the food had been on the street for quite some time, Lin Hai had to use a lot of effort to swallow the cold food, then praise the hostess for her good cooking skills and tease her that the host must have done good deeds in his previous life to marry such a good wife, and then repeat the process at the next family's door.

Lin Hai could only trust his stomach. Otherwise, if he died of diarrhea, he would probably become internal training material for the Eagle Control Guard and the Embroidered Uniform Guard and be laughed at for hundreds of years.

The praised family would be proud of themselves in front of their neighbors. The hostess would stand at the door and loudly boast that her excellent cooking skills had been recognized by Qinghebo, while the host would say that he was indeed a first-class man, and even Qinghebo praised him. He would even hint that it was your fault that you didn't marry me back then...

Then, when they returned home, they would serve the dishes that had been warm on the stove, and the family would gather together to enjoy a hearty meal. As for the "delicacies that Qinghe Bo had personally eaten" that were almost frozen on the doorstep, the frugal people of Qinghe would naturally not throw them away. They would use them as high-quality ingredients to feed dogs and pigs.

As for the merchants, it is much easier to deal with.

Early in the morning, the merchant owners who received the notice brought their shopkeepers, caravan leaders, accountants and other people to wait at the door of their shops. No matter how the unfriendly brother and the soldiers of the first regiment searched the shops, they did not show any displeasure.

When Lin Hai arrived, they couldn't wait to take out their signature products and vividly explain them to him. Of course, no one expected Lin Hai to spend money at this time, but if their products received a "good" word from Qinghe Bo, then these businessmen who were well versed in business would do their utmost to turn this word into silver.

During the Chinese New Year, Lin Hai was not stingy with his praise. He praised the products from East No. 10 Shop to the end of the street. He even divided the praise into four levels: "good", "very good", "very good" and "this is not bad, I will buy some when I have time" based on the importance of the products to Qinghe, the amount of taxes paid by the merchants, the number of employees and other information.

No one would really believe that Lin Hai would "come and buy some when he has time", but as long as he said that, it was enough. Lin Hai believed that with the acumen and execution ability of these businessmen, a lot of products that "Even Uncle Qinghe said were good" would emerge in Qinghe that afternoon.

As for the merchant who had gone through so much trouble to transport his products to the northern border of Liang State and sell them to the barbarians, Lin Hai spent a long time listening to the merchant owner and the caravan leader describe in detail the various hardships of going north, and carefully inquired about the poverty of the barbarians and their habit of exchanging gemstones and agates for knives and glass beads. Finally, he agreed to let them hire retired Qinghe soldiers and purchase a certain amount of standard weapons and equipment to protect the caravan, and left a calligraphy with the four big characters "cutting through thorns and brambles".

After hearing about Lin Hai's behavior, more than one or two merchants became jealous. According to Ling Yang's report afterwards, more than ten merchants formed a caravan heading north that day, and planned to register with the Ministry of Commerce after the new year, and then gather into an unprecedented large caravan heading north.

Lin Hai expressed his satisfaction with this, and it seemed that his performance was sold at a good price.
