Volunteer management website front-end + back-end
Respond to questions:
In the first article I mentioned 200 yuan for a private job of an HDFS file manager. In the article, it was said that I had done something similar before and just took it and delivered it. 200 yuan is considered a waste of money. Of course, this also takes time. After accumulating so many orders, there are always a few orders that sell the finished product directly at a customized price. This is also a small skill for receiving orders. Below is the link to the original text:

Summarize
The above is to use the code generator to generate the sharing of the background of the volunteer management system. Use the code generator to automate the typing of codes that you don't need to know. Or, that sentence can't make you rich and rich, and it is still very easy to earn some pocket money.
