The results of the mutual aid survey conducted by China Survey Network are not credible, because members vote only to earn gold coins, and few people vote with their hearts, but they do make money. Of course, there are many survey websites that can make money. Is the China survey network very good? I'm interested in going to the global survey network. There are many survey websites recommended by it, all of which are very good. Only then did I know that online investigation was a part-time job.
