What are the incomes of part-time extras and TV viewers in Shanghai? Is the information on the Internet true or false?

To tell the truth, it's hard to tell whether the part-time information on the Internet is true or false, and it's not excluded to cheat money and color.

The income of extras and TV viewers is not high and it is very hard. Let me give you an example. The extras will gather at five o'clock in the morning when they go to the set. Usually they can't start giving you activities until the afternoon, so they have to wait all day. Because we have to shoot famous actors and protagonists first.
