My friend, the free credit you mentioned is Cheng e Credit.

You can enjoy three benefits by opening Cheng e Credit:

1. Increase store traffic, search ranking, special market priority, and increase store exposure

2. Get high-quality buyers, all of whom are Taobao sellers above diamond level and members of Chengxintong

3. Credit weighting, Cheng e Credit orders are helpful for credit assessment

Of course, although there are benefits, there are also certain disadvantages. It is very inconvenient for the company to reconcile accounts, and the probability of disputes will increase accordingly
