CHAGEE mini-program crashes during Zheng Qinwen victory promotion

The official mini-program of tea chain CHAGEE experienced a technical crash due to a massive surge in traffic. The outage occurred following the launch of a ‘buy one get one free’ promotion to celebrate brand ambassador Zheng Qinwen winning the women's singles title at the China Open.

Store employees in Beijing reported extreme congestion, with some locations receiving over 200 orders within 40 minutes of opening. While third-party platforms remained functional, the promotional discount was exclusively available through the CHAGEE mini-program for both dine-in and delivery services.

Zheng Qinwen made history as the first local player to win the women's singles title at the China Open, securing her first WTA 1000 title. The promotion was limited to one use per ID and applied to all drinks, including gelato, across most national stores.
