problem description

is going to crawl the penalty information of several listed companies on the Shenzhen Stock Exchange website in a multi-process way at the same time, but the code is only executed on one of the listed company names, which is very confusing.

I would like to ask if the following changes should be made, and what can be optimized in the code. Thank you very much!

the code is as follows:
