On May 31th, just after the Dragon Boat Festival holiday, two old Chongqing Jumantang hotpot restaurants located in Jing 'an Road and Gui Hu West Road in Xindu District suddenly closed.

At the scene, a seal with the words "Xindu District Market and Quality Supervision Administration" was printed on the door of the hot pot restaurant, which attracted people from the past to stop and watch. Some netizens uploaded the news and photos of the hot pot restaurant's closure to the Internet, and the issue that Jumantang hot pot restaurant was sealed after it was exposed that it used old oil in Jinjiang District (Weibo), Chengdu, also attracted attention.

It is understood that Chongqing Jumantang Old Hotpot Restaurant is well-known in Xindu, with franchise stores in Xindu, Longquan, Pidu, Qingbaijiang and High-tech Zone, among which the store located in Jing 'an Road in Xindu belongs to Jumantang Old Hotpot Restaurant. "It's delicious. Business is still very hot during the Dragon Boat Festival this year. I have diarrhea after eating twice. I wonder if it is related to old oil." Xiaoliang, a citizen of Xindu, said.

On June 3rd, it was confirmed by Xindu District Market and Quality Supervision Administration that Chongqing Jumantang Old Hotpot Restaurant had been sealed up by law enforcement authorities for using old oil.

According to a law enforcement official, before the Dragon Boat Festival this year, we received a report from the masses that the old Jumantang hotpot restaurant in Xindu used old oil. "The other party provided us with relevant evidence, including the Jumantang hotpot store in Jing 'an Road, Xindu, and the Yinmahe Gui Hu store in Gui Hu West Road."

After preliminary cooking, at noon on May 31th, during the peak dining hours that day, the market and quality supervision and management department of Xindu District, together with Xindu police, conducted a surprise inspection on two stores, and seized about 911 kilograms of old hot pot oil boiled with kitchen waste and waste grease, as well as some production tools, and stopped more than 21 suspects on the spot. "In this inspection, we found a lot of cooking tools that we couldn't see during the usual inspection. Combined with the evidence provided by the whistleblower, law enforcement officers intercepted 21 suspects, including liuyong and Wang Dongliang.

after the trial, the suspect confessed that in order to reduce operating costs and obtain higher profits, the waste oil was used to produce edible oil. At present, 111 suspects have been criminally detained by Xindu police according to law.
