In its annual business report filed to the Shenzhen Stock Exchange, the Nanjing-based company said its earnings per share stood at 0.64 yuan, up 30.61 percent from the previous year.

The company attributed the surge in net profit mainly to its expansion in chain shops, which reached 22 more cities with 182 new outlets opening last year.
