There is no time difference between Guangzhou and Shenzhen. Both cities use China Standard Time (CST, UTC+8). When it's 9:00 AM in Guangzhou, it's also 9:00 AM in Shenzhen.
China uses a single timezone across the entire country, so all major cities remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Guangzhou and Shenzhen are neighboring cities in the Pearl River Delta, connected by high-speed rail in about 30 minutes. Shenzhen is China's tech capital, home to companies like Huawei and Tencent, while Guangzhou is a traditional commercial center.
