Who was Brewmaster in the hotel poster in Song Dynasty?

Lu slipped to the foot of Wutai Mountain, thinking that he could have a full kiss, but he refused to sell him wine even after going to three or five hotels. He had to pretend to be a "monk of the past" and finally had a drink in a remote village shop. There is a poem in the book that describes this hotel like this: "It has been near the hotel in the village for many years, relying on the Sangma ancient road. White benches are for guests, and fences must be made of thorns. Broken urn pressed into yellow wine, Chai Men picked out the curtain. More laughter, the mud wall is Brewmaster. " This is probably the typical layout of township hotels in Song and Yuan Dynasties. Interestingly, a poster was posted on the wall of this humble village shop, and "Brewmaster" was painted on the "cow excrement mud wall". Many small hotels in the Water Margin have such posters. The sixth time, after Lu and Shi Jin burned the crock temple, they came to a small hotel, also Chai Men, with a curtain, a wine jar and a dust wall. On the wall, there are both the Chinese characters "When the village scholar is drunk" and the words "The immortal in ink painting". Back to the 32nd time, Song Wu fled Mengzhou dressed as a monk and went to a small hotel in the next village of Baihu Mountain. Because it is winter, the wine flag flutters with the wind, "a cold wind dances in the green", and the layout in the room is nothing more than: "Wupi tables and chairs, all lined with pottery bowls, magnetic ou; Brewmaster poets are painted on the loess walls. " Now, Song Sigong makes a scene, which is an old song of Song and Yuan Dynasties. There is a passage describing Song Sigong's coming to a country hotel, and the praise describing this hotel is similar to that describing the one where Lu and Shi Jin entered. The poster on this wall is "drunken fairy", which is more appropriate than "fairy", and "painting" is more like "fairy". Who are these "Brewmaster poets" and "drunken immortals"? On the 29th, when they went to Happy Forest, Song Wu and Shi En ate more than a dozen restaurants. Among them, the praise for the first restaurant-some versions of Water Margin didn't have this praise-was like this: "Liu Ling was greedy on the wall, and Li Bai handed a cup by the window. When Yuan and Ming returned, Wang Hong sent wine to Dongli; Fo Yin lived in the mountains, and Su Shi fled Zen to beige. " Stories about Liu Ling, Tao Yuanming, Li Bai, Su Dongpo, Fo Yin and others who were addicted to alcohol were widely circulated. Liu Ling wrote Ode to Wine Virtue, which Li Bai called "Hundred Poems on Fighting Wine", Tao Yuanming wrote a group of drinking poems, and Su Dongpo wrote such famous works as Wine Classic, Ode to Hunjiu and Ode to Spring in Dongting. He described a novel called Ode to Wine as an excellent advertisement for painting these Brewmaster and poets on the wall. Tokyo Chinese Dream, Jingshi Jisheng, Liang Lu's Dream and Riverside Scene at Qingming Festival all record the grand occasion of Bianjing Lin 'an. If you want to know the characteristics of local and township hotels at that time, you have to pass on works from people like Water Margin.
