How about Nanjing College Students' Social Practice Network? The one in the new world center.
Not bad. I went after the college entrance examination last year. I earned more than 1000 from scratch, that is, I made it once or twice in ten days and a half months or if I wanted to buy something. I won't lose money anyway. I have something to do every day as long as you like. As long as you are not afraid of being tired and meet a better job, sometimes you can earn one or two hundred yuan a day.
