There is no time difference between Beijing and Hong Kong. Both cities use the same timezone (UTC+8). Beijing uses China Standard Time (CST) and Hong Kong uses Hong Kong Time (HKT). When it's 9:00 AM in Beijing, it's also 9:00 AM in Hong Kong.
Neither city observes daylight saving time, so they 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 - 6:00 PM) without any time conversion needed.
Beijing and Hong Kong are connected by high-speed rail (approximately 9 hours) and frequent flights (about 3 hours). As major financial and political centers, business coordination between the two cities is constant.
