Do you know anything about the engineering guarantee industry? Which is better, Shenzhen Zhongheyin or Shenzhen Yin Da? I'm ready. I'm struggling. . . .

Do you want to be a salesman? These two companies are similar, and China United Bank is a little larger. Changan Guarantee, SZITIC and Hi-Tech Investment are all big-name guarantee companies. I don't know the income of salespeople there. Now the guarantee market is very mature and the price competition is fierce. A good salesman's income is still ok.
