The Yiche are part of the Hani nationality in China. Yiche women are unique among all the peoples of China because they wear shorts. They also wear conical hats, similar to the Jino people, and shortsleeved blue blouses held together by five-colored girdles. "The clothes are layered one on top of each other, numbering from six to more than a dozen. ... The layers indicate a family's financial standing. Women wear black shorts with pleats at the legs."

Little is known about the origins of the Yiche people, because they have never possessed a written script. Legends are handed down orally from generation to generation. The Yiche say they were once part of a tribe of 7,000 families, living "on a vast fertile plain away in the east where the sun rises."

Yiche houses are two stories high and have tiled roofs. The upper floor serves as a storehouse and the lower floor as the living quarters. Every year in the fifth lunar month the Yiche celebrate the Kuzhazha Festival. "According to traditional custom, every family must light pine torches after sunset. Burning torches in hand, they walk around the house to perform a 'mopping up' and then follow a forked chestnut rod to the top of the road outside the hamlet and place the torches beside the chestnut rod. This drives evil away from the house ensuring the coming year is filled with peace and happiness."

The Yiche are polytheists. "Most of their villages have temples where a multitude of gods are worshipped. These gods are associated with the earth, water, and fire, as well as famous ancestors. It is common for brothers of the same family to worship their dead parents at the eldest brother's house." On the lunar New Year's Eve, Yiche children hear stories about their ancestors and learn their family genealogies.

Some parts of Honghe Prefecture experienced a mass people movement to Christ in the 1940s as a result of the labors of missionaries. During the Cultural Revolution great persecution broke out against the church. Many fledgling believers fell away, but others "conducted Sunday services in cattle stables or on mountain peaks." Today most believers in the area are Kado or Biyo, but there may be a few Yiche Christians.
