Mosuo culture is primarily agrarian, with work based on farming tasks such as raising livestock (yak, water buffalo, sheep, goats, poultry) and growing crops, including grains and potatoes. The people are largely self-sufficient in diet, raising enough for their daily needs. Meat is an important part of their diet and, since they lack refrigeration, is preserved through salting or smoking. The Mosuo are renowned for their preserved pork, which may be kept for 10 years or more. They produce a local alcoholic beverage made from grain, called "sulima", which is similar to strong wine. Sulima is drunk regularly and usually offered to guests and at ceremonies and festivals.
