It is true that you can earn money by doing questionnaires first. At present, it is very popular to participate in paid surveys online. There are many survey websites in China, some of which are very powerful, such as the first survey network and other formal market research stations, while others are not powerful and difficult to survive, so it often happens to cheat members. However, if you join a regular and powerful investigation website, you can earn money by working part-time with confidence. A website like First Survey, which specializes in doing business questionnaires, can be done with confidence. They do a lot of research, and the rewards are quite timely. The most important thing is that they have a good reputation, so many people visit it.
