A recent study conducted in the Xin Jiangwancheng community in Yangpu District found that learning to use APP on smart phone has become a compelling need for the elderly. The unfamiliarity of APP use on smart phones has rendered itself a great inconvenience to the elderly, especially when they need to communicate with their family members via social networking software like Wechat. Even still, there was no way for them to use the food-purchasing machines which were meant to facilitate their lives within their community.

In light of this problem, volunteers from the Association of Harmonious Society of Tongji University worked out a lecturing plan for the community based on its current situation and went to the community to carry out its teaching activities. They focused primarily on the illustration of Wechat use and some other APPs related to the daily shopping of the old, as required by local neighborhood committee.
