Taoism has the legend of cave heaven and blessed land. The world of immortals is composed of ten big caves, thirty-six small caves and seventy-two blessed places. Sichuan cuisine also has the legend of gardens, halls and halls. Zhengxing garden, Rongyuan paradise and Zhongdian building are the schools for cooks. It is the famous little Dongtian hotel in Chongqing that can connect two unrelated legends together. The signboard of xiaodongtian hotel is built by two generations of Sichuan cuisine chefs separated by 30 years. They have superb cooking skills and dishes. There are glories and gloom, expansions and regrets. Until the curtain call 15 years ago, it is still the Holy Land in the hearts of pilgrims.
