I am a man who studies computer science. I would like to ask if working as a secretarial (clerk) in Jiujiang for 600 yuan a month with food included is worth it?

I suggest you consider other places. The salary level in Jiujiang is really not flattering. Because it is a tourist city, the consumption level is even more terrifying. If you want to have some money in your wallet and bank card To save money, consider moving to bigger cities, such as Wuhan and Nanchang. The salary of 600 yuan in Jiujiang should be considered mid-range.
