Am Johnson, I want to travel to find teaching job to do. What type of visa should I apply for

Johnson, you can apply for a tourist L type to enter PRC to find the teaching job. But after finding a job, you need to apply for a work Z type.

You should first prepare the required materials including your passport and copy of its data page, the application form, a passport-style photo, round trip air tickets and accommodation reservation, original bank statement within latest four months, an invitation letter for tourist issued by an authorized tourism unit in PRC, and a personal introduction letter.
After, submit the application to the embassy of PRC to apply for the tourist L type.
