first fought against the Nurhaci and the Manchus, led by their own Nanai Hurka chief Sosoku before surrendering to Hongtaiji in 1631. Mandatory shaving of the front of all male heads was imposed on Amur peoples conquered by the Qing like the Nanai people. The Amur peoples already wore the queue on the back of their heads but did not shave the front until the Qing subjected them and ordered them to shave. The term "shaved-head people" was used to describe the Nanai by Ulch people. Economy As described by early visitors (e.g., Jesuit cartographers on the Ussuri River in 1709), the economy of the people living there (who would be classified as Nanai, or possible Udege people, today) was based on fishing. The people would live in villages along the banks of the Ussuri, and would spend their entire summers fishing, eating fresh fish in the summer (particularly appreciating the sturgeon), and drying more fish for eating in winter. Fish would be used as fodder for those few domestic animals they had (which made the flesh of a locally raised pig almost inedible by visitors with European tastes). The traditional clothing was made out of fish skins. These skins were left to dry. Once dry, they were struck repeatedly with a mallet to leave them completely smooth. Finally they were sewn together. The fish chosen to be used were those weighing more than 50 kilograms. In the past centuries, this distinct practice earned the Nanai the name "Fish-skin Tartars" (, Yupi Dazi). This name has also been applied, more generically, to other aboriginal groups of the lower Sungari and lower Amur basins. Agriculture entered the Nanai lands only slowly. Practically the only crop grown by the Yupi villagers on the Ussuri River shores in 1709 was some tobacco. Religion The Nanai are mainly Shamanist, with a great reverence for the bear (Doonta) and the tiger (Amba). They consider that the shamans have the power to expel bad spirits by means of prayers to the gods. During the centuries they have been worshippers of the spirits of the sun, the moon, the mountains, the water and the trees. According to their beliefs, the land was once flat until great serpents gouged out the river valleys. They consider that all the things of the universe possess their own spirit and that these spirits wander independently throughout the world. In the Nanai
