Against the frost risk in Jiaxing
Why these dates
Sow direct three weeks before the last frost where it is to flower. It has a short season, roughly five weeks, so sow in succession every three weeks for a continuous show. Cut back hard after flowering and a second flush sometimes follows.
Hardy to about -10C, so it can be autumn-sown in zone 7 and milder for late spring flowers. Finishes quickly once the weather turns hot.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Candytufts are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Jiaxing.
Hardiness is not the obstacle here. Jiaxing is zone 9a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 280 days, against 55 to 75 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
