Shanghai-based law firm Llinks Law Offices, one of China’s most profitable firms, has become the latest to launch an office in Shenzhen, China’s technology center and an increasingly popular base for Chinese and global law firms.

The new office is starting out with four partners from rival Chinese firm AllBright Law Offices. The group is led by partner Alex Huang, who joins with partners Candice Du, Alan Chen and Sheldon Chen and a dozen additional lawyers.
