Jacaranda season in Kunming

China's biggest holiday. In the run-up, Kunming's Dounan Flower Market 斗南花市 sells armfuls of blooms for the home, families gather on New Year's Eve for a reunion dinner, and in the first days of the year temples such as Yuantong Temple 圆通寺 fill with people burning incense for luck. Warm Xishuangbanna and the old towns of Dali and Lijiang are favorite holiday escapes for families from across China.

How to join: Visit a temple on the first or second morning of the year, walk a flower market, or ask to share a family's reunion dinner. Book trains and rooms well ahead: this is the busiest travel period of the year and prices climb sharply.

Etiquette: Wish people 'xin nian kuai le' (Happy New Year) and avoid talk of death or illness. Many small restaurants and shops close for the first three days.

Yunnan has hundreds of rhododendron species, and in spring whole hillsides turn pink, red and white. The bloom climbs with altitude: Zixi Mountain 紫溪山 near Chuxiong flowers from April, the upper slopes of Cangshan above Dali follow, and the meadows and forests around Shangri-La, including Pudacuo National Park 普达措, peak from late May into June.

How to join: Walk rather than just stopping at a viewpoint: the Cangshan cable car takes you up to the high slopes, and the Pudacuo boardwalks pass through rhododendron forest. Bring rain gear, as the rainy season starts in June.

Etiquette: Don't pick flowers or break branches.

The Zhuang's spring festival honors ancestors and the new season with call-and-response singing, bronze drums, five-color sticky rice and shared meals. In Wenshan it is kept in Zhuang villages around Guangnan 广南, including Bamei 坝美, and in Funing 富宁.

How to join: County towns often hold public singing contests and markets on the day. For a village celebration, go with a guide or host who knows the families.

Etiquette: Accept the five-color rice when it is offered, and join the listening crowd rather than pushing to the front to film.
