The fishy smell agent was found to contain harmful substances. Douyin blogger Leshan Eel Dawa live broadcasts catching eels in the field, using his fishy smell agent to lure the eels out. As long as the eels show a little bit, he will catch them. Sometimes the eel would run away if he couldn't catch it firmly. At this time, he would say "don't panic", then judge the eel's position and stick his bare hands into the mud to catch the eel again. However, on June 17, 2022, the smelly agent in his home was found to contain harmful substances that would pollute water resources, and the smelly agent was banned. The live broadcast of Leshan Eel Dawa in the wild was also temporarily banned.
