Why do many rental information leave no real phone number, but is it credible to add WeChat?

The phone is just afraid of harassment.

Wechat can talk first. Renting a house ultimately depends on looking at the house. Believe it or not. You'll know when you see the house.

Some housing information is fabricated by the intermediary (generally low price and good location). When asked, it may be said that it has been rented out, but it can be introduced to other houses. This is the real purpose.

It is necessary to remain vigilant.
