Can I still play QQ Modern City?

No. Tencent has officially stopped the game operation of "Modern City" in mainland China on May 30, 2016. As of July 26, 2023, it has not been re-launched, so it cannot be played. "Modern City", a subsidiary of Tencent Games, is a 2D simulated city management community game. It covers multiple gameplay methods such as growing agricultural products, selling supplies, operating hotels, and interacting with friends.
