Eating big noodles in stocks actually comes from the saying "turn off the lights and eat noodles". In fact, it means that the stock plummets or the stock drops to the limit.
Because in 2011, the listed company Chongqing Beer issued an announcement announcing that the hepatitis B vaccine that the company had invested heavily in the development of for 13 years had been evaluated by clinical trials as having no significant efficacy, causing the stock price to rise sharply. It fell, with the word "one" falling by the limit for 9 consecutive times. The stock price fell from 80 yuan to 20 yuan, and the market value of more than 20 billion yuan evaporated instantly.

On December 7, 2011, the Chongqing Beer Black Swan incident broke out, triggering continuous limit drops and the stock price falling sharply. On December 15, on the night when Chongqing Beer experienced its sixth consecutive "1" drop, a netizen from the Oriental Fortune Online Stock Bar published a post titled "Eating and Crying at the same time" in a Chongqing Beer Bar.
The content of the post is very simple, with only one short sentence - I went home today and cooked some noodles to eat. I cried while eating the noodles, and my tears fell into the bowl without turning on the light. There was not a word of complaint, a word of curse, a word of grief, anger, or pain from this stock investor, but his state of being numb with sorrow and tortured soul and body was vividly portrayed in just one sentence.
