In the past, it was the kiln mouth for the production of porcelain. It was transported along the Jialing River by a ship and a ship to the lower reaches of the Yangtze River. This work has been liberated, so the magnet mouth can survive. On the side of the road, talking about the pure-style old man of the Freestyle version of the Sichuan dialect, while greeting the guests with Rap, while rhythmically tapping the palm of the hand to the stainless steel leaking basin, the pot is made of hand-made purple potato powder, the old man Purple sweet potato powder is drawn along the leak hole, and a purple line instantly slides into the earthen jar below, and Nirvana becomes a smooth and smooth hot and sour powder. In this way, using the "Ancient artifacts" combined with rap to make the hot and sour powder, I feel very hopeful to join the Shapingba intangible cultural heritage list. Drinking is not only hot and sour powder, snacks from all over Chongqing have moved here, so please be welcome when faced with all kinds of trials.
