Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.

Quinces through the year
Against the frost risk in Shijiazhuang
Why these dates
Plant dormant. Quince flowers noticeably later than apple or pear, which makes it a sensible choice in a frost pocket where the earlier-blooming tree fruit keeps losing its crop.
Quinces are planted once and then left in place, so there is no sowing offset to resolve. What matters in Shijiazhuang is the shape of the year: this crop is dormant through the winter and is planted while it sleeps, any time between leaf fall in autumn and the restart of growth in spring, so long as the ground is neither frozen nor waterlogged. That is why the window below spans the cold months rather than sitting in the middle of the growing season.
Hardiness is not the obstacle here. Shijiazhuang is zone 7b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 4, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
