HANGZHOU: In a compact shop no larger than 10 square meters, Tao Yang, a vendor in Yiwu — a city in Zhejiang province known as "the world's supermarket" — keeps a well-used world atlas on her desk.
"I ask my customers to sign their names over their home countries," she says, adding that she has collected signatures from clients in 20 countries. "Our doors are always open to the whole world."
