Which city in China is suitable for the development of young people from other places?

If you want to go to the south, I suggest you go to the torch area in Shenzhen or Zhongshan.

There are many Japanese companies in Shenzhen, and the company system that specializes in supplying two Japanese cars (Honda and Toyota) is huge. Besides, you are a mechanical major, so it is not a big problem to find a job. Japanese companies in Shenzhen are generally treated well, and the labor department is also very strict with them, but the price in Shenzhen is a bit high, so you can consider it.

The other is the Torch District in Zhongshan, where some well-known Japanese enterprises gather, such as Canon, Eight Hundred Generation, Yuechi and so on. You can search on Zhongshan International Talent Network.

Of course, the above are just suggestions, and ultimately it depends on your own ideas and actual situation. good luck
