Elderly residents of a Korean ethnic community in Northeast China's Jilin province attach yellow ribbons to their windows, a sign that they need assistance.

At the beginning of her day, Wang Shuqing, chief of the Danying community in Yanji, gets up at 5:30 am to walk around the area.

"I need to check if any ribbons are tied to windows and see what I can do to help," Wang said.

Yanji, capital of the Yanbian Korean autonomous prefecture, home to the greatest concentration of ethnic Koreans in China, has seen large numbers of its young people leave for the Republic of Korea or China's eastern and southern regions to seek jobs. The elderly are often left behind, living alone in empty nests.

Yanbian prefecture has an estimated population of 350,000 elderly, and its government is coping with the situation in various ways, including the introduction of the yellow ribbons.

Wang said there are more than 900 empty-nesters, about 10 percent of the residents, in her community.

The elderly may need assistance in their homes or with some shopping. But the yellow ribbons are far from enough, especially when there's an emergency, Wang said.

Telephones have been modified so that the elderly can contact community workers by pressing a single button.

In rural areas, the situation is more difficult for empty-nest families.
