For a classic city route
Spring and autumn are useful starting points for a Beijing–Xi’an–Shanghai plan. Check local weather averages and your tolerance for heat, cold or rain before choosing exact dates.
For mountain scenery
Allow flexibility for cloud and rain in places such as Zhangjiajie. A buffer day is more useful than promising a particular view on one fixed morning.
For family trips
Balance school dates with weather and crowd tolerance. Fewer hotel changes and an air-conditioned afternoon break may help more than trying to fit in another attraction.
Watch the calendar
Check China’s published holiday dates for your travel year. Transport and hotel availability can change around major holidays. Book key journeys only after checking the current schedule and cancellation conditions.
