During the five trading days from April 16 to April 2, Tonghua Jinma closed down for four times, and fell 9.92% again on April 23. What's more, the company's performance was hit hard by the poison capsule incident.

Pit index: ★★★★☆

Shuanghui Development falls into the "maggot door" again

Pit index: ★★☆

Event review: Shuanghui Development, which suffered from clenbuterol incident in 211, broke out quality problems again this year. On May 27th, some consumers claimed that Shuanghui ribs were infested with maggots, and the related news was reprinted in large numbers on the 28th. On the 29th, Shuanghui issued a statement denying the "maggot" incident. In fact, in addition to this incident, Fuzhou, Jiangxi, Zhengzhou and other places all broke the news that maggots were found in Shuanghui development products this year.

Impact of the incident: Compared with the tragic situation that the clenbuterol incident broke out last year, investors who have already had certain "resistance" seem to be quite calm about the "maggot gate" of Shuanghui's development. During the period from May 28th to 31st, the cumulative decline of Shuanghui's development was only 1.19%. However, with more and more food quality problems pointing to Shuanghui's development, the share price of Shuanghui's development finally fell sharply at the end of August.
