Last year, he worked in Yiwu and Nanjing for one month as an electric salesperson and one month as a customer service representative. My younger brother has been working in Chengdu for half a year now. He is currently employed at the hospital's operations department. He usually does cold calling. He seems to be much more hardworking than me. I also want to work hard and find a job somewhere in Shenzhen. Does Shenzhen generally offer health insurance?
