There is no time difference between Shenzhen and Beijing. Both cities use China Standard Time (CST, UTC+8). When it's 12:00 PM in Shenzhen, it's also 12:00 PM in Beijing.
China uses a single timezone across the entire country, so all major cities remain synchronized year-round. China does not observe daylight saving time.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Shenzhen and Beijing represent different aspects of China - Beijing is the political and cultural capital, while Shenzhen is the tech and manufacturing hub near Hong Kong. High-speed trains connect them in about 8 hours, while flights take about 3 hours.
