Does the branch of the property company need to apply for qualification separately?

It does not need to be handled separately because:

According to the company law

Article 14 Branches and subsidiaries may set up branches. The establishment of a branch company shall apply to the company registration authority for registration and obtain a business license. A branch company does not have legal person status, and its civil liability shall be borne by the company.

A company may set up subsidiaries, which have legal personality and independently bear civil liabilities according to law.
