The city's civil affairs bureau has required the shelters, which provide food, clothing and heating, to acquire more quilts and heating equipment, said bureau director Li Zhizhen.

Civil affairs bureaus at the district and county levels and rescue organizations were called upon to patrol the city to identify those in need, as well as to visit low-income households, Li said.

Attempts will be made to persuade the homeless to make use of the shelters. Those who refuse to go will be provided with food and clothing to help them keep warm.

Social welfare homes, nursing homes and mental hospitals affiliated with the bureau will receive more stockings, hats and heaters.

Non-government organizations and volunteers are being encouraged to help those in difficulty, while an emergency alert system will monitor the elderly who live alone.

The civil affairs bureau has 1,000 heaters, quilts and clothing available for those in need, Li said.
