Every Tuesday and Thursday, uncles in Shanghai will rush to the "Dating Corner" of the IKEA restaurant in Xujiahui. They will sit down early and chat with the grandmothers they know or search with their eyes hidden behind dark lenses.
Some people have adhered to this kind of life pattern for more than ten years. "I came here to observe human beings. I like to communicate with different people," says Uncle Chen, who was born in the 1960s.
