Best overlap: 4:00 PM to 6:00 PM in Shenzhen is 8:00 AM to 10:00 AM in Manchester.
Keep meetings inside 4:00 PM to 6:00 PM in Shenzhen — that maps to 8:00 AM to 10:00 AM in Manchester. Since Manchester is 8 hours behind Shenzhen, the overlap is narrow (about 2 hours); a single, well-protected slot beats hunting for time each week. These times hold for most of the year, but Manchester's daylight saving (which Shenzhen doesn't use) shifts them by an hour twice annually.
