Hangong Hotpot was extremely popular during the period of the Republic of China. Especially, its cattle stomach made a household name. The rumor goes that when night fall, people go to eat cattle stomach at Hangong Hotpot restaurant and go home, drunk and supported by the others. It made a dramatic turn and disappeared all of sudden during the 1940s and 1950s. 

Driven by opening-up reform, Chongqing’s hotpot industry saw a booming period. Li Daizhong, an excellent cook for hotpot, brought Hangong back to its golden period with his 20 years of dedication, aiming at inheriting hotpot culture and recollecting the past. The hotpot has been passed down through generations to this date. Chongqing Hangong Catering Management Co., Ltd. purchased this brand by overcoming difficulties and renamed it the Past of Hangong with an awe of its reputation. Nowadays, the Past of Hangong has been a famous brand in Chongqing and a time-honored brand in China, with its presence across China.
