Why didn't Song Dynasty officials dare to eat and drink in hotels?

Throughout the ages, there will be some old rules explicitly stipulated or established, which are called old systems, stories or allusions in history books. Some old rules, such as those of the Song Dynasty, standardized the behavior of officials to a certain extent, and suppressed the overflow of power. One of the old rules: "Officials don't enter restaurants." In the Song Dynasty, although the catering industry in Kaifeng, the capital, was very developed, and hotels were all over the streets, officials were afraid to eat and drink in hotels, because once officials were in hotels, regardless of public funds or private funds, they would be impeached by Yushi immediately, either dismissed or disciplined. According to the Record of Returning to the Field, Lu Zongdao, the teacher of Prince Song Zhenzong, once had a guest in his hometown. Because there was no wine at home, he had to change into casual clothes, and led the guest to Renhelou Hotel for entertainment, wandering between gentry and vendors. It happened that Song Zhenzong had something urgent to summon him on this day. When he slowly arrived at the palace, Song Zhenzong really asked, "Why did you enter the restaurant privately?" He also said, "Qing is an official, and I am afraid that it will be played by the imperial history." If Lu Zongdao hadn't told the truth and pleaded guilty, he would have almost lost. The second old rule: "Don't eat from all directions". In the Song Dynasty, princes and nobles were forbidden to eat in the four corners, which meant that those in power were not allowed to ask for local specialties and delicacies from all over the country to prevent arbitrary expropriation. According to Shao Lu Wen Jian, once she was ill, the queen wanted to find special products from Jianghuai area to supplement the emperor's body, but she searched all over the capital and found nothing. When you are sad, it happened that the wife of Prime Minister Lv Yijian went to the palace to pay her respects to the Queen. Remembering that she was from Shouzhou (now Shouxian County, Anhui Province), the Queen said to Mrs. Lu, "The ancestors ate white fish well. This is an old rule. You can't eat it from all directions, and there is no way to cause it. Shouzhou, the "xianggong family", should be there. " Lv Yijian's family has. When Mrs. Lu got home, she quickly sent the bad white fish to the palace, fulfilling the queen's wish. It can be seen that an obscure old rule, as long as it is well implemented, even the mouth of the supreme emperor can be controlled. Rule 3: "Don't kill the scholar-bureaucrat or the speaker in the letter". The oldest and most effective old rule in the Song Dynasty was the well-known Song Taizu's oath: "Don't kill literati and writers." Although this oath is only an ancestral family rule, it is superior to any policy and law. For more than 300 years before and after the Song Dynasty, it was rare to operate on literati and national political critics, and even to repeatedly change the rules because of this old rule and put people under the sword. When Su Dongpo was almost punished according to the crime for opposing Song Shenzong's political reform, just as the butcher's knife was about to be lifted, Song Shenzong suddenly thought of the ancestral motto of "Don't kill literati and writers", and finally had to crush his inner anger, actively remonstrate and demote Su Dongpo. Su Dongpo also saved a life from a dead end because of this old rule. Further reading: How did Li Ling, the prime minister of the Song Dynasty, burn the imperial edict on his face?
