Yi Costume Festival at Zhiju

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.

Tibetan families in Shangri-La and Deqin clean their homes, make offerings and hang new prayer flags, then spend the first days of the year visiting relatives, monasteries and sacred sites. Many Diqing households also keep the Chinese Spring Festival, so the holiday mood lasts for weeks.

How to join: Walk the pilgrim circuit around Songzanlin Monastery 松赞林寺, or join the evening circle dancing on the square in Dukezong Old Town 独克宗古城 when it's on. Some family guesthouses close, so book ahead.

Etiquette: Go clockwise around monasteries, stupas and prayer wheels. Don't touch offerings, and ask before photographing anyone at prayer.

For more than two centuries Lisu families from up and down the canyon have gathered at the Denggeng hot springs 登埂澡塘 north of Liuku in the first days of the lunar year, bathing to wash away the old year's ills and camping by the river between soaks, with singing contests and food stalls.

How to join: Come by day from Liuku, where rooms are easier to find, and bring swimwear and a towel. The hidden Nujiang Canyon route passes the springs on Day 1.

Etiquette: Wear swimwear, keep to the public pools, and ask before photographing anyone in the water.
