There is no time difference between Guangzhou and Singapore. Both cities use UTC+8 - Guangzhou uses China Standard Time (CST) and Singapore uses Singapore Standard Time (SGT). When it's 9:00 AM in Guangzhou, it's also 9:00 AM in Singapore.
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 - 5:00 PM) without any time conversion needed.
Guangzhou and Singapore are connected by direct flights taking about 4 hours. Both are major Asian trade hubs with significant Chinese populations and strong business ties in manufacturing, finance, and logistics.
