On which websites do corporate HR generally search for training lecturers?

I want to know whether you recruit temporarily or permanently ~ ~ I'll tell you a method. You can find a company recruiting corporate trainers on big talent websites such as Zhitong or Zhuo Bo, and then you can find a lot of information. You can find the nearest one, or you can post fake recruitment information, but if you don't recruit, many people will definitely give you information. Just choose the nearest one and have a look. I am a perennial HR, and there is absolutely no problem with what I said. I wish you an early settlement.
