HONG KONG -- Chen Lulu, a migrant worker raising a 3-year-old son in the southern Chinese city of Shenzhen, knows where to find a bargain. She buys everything from an umbrella to toilet paper on Pinduoduo, an online shopping site known for cheap products. At the supermarkets of the tech metropolis, the same items are beyond her means.
Chen, who hails from a poor village in Anhui Province, has worked at a small nail salon near the city center since 2015. The 27-year-old pays 3,000 yuan ($436) a month to rent a two-bedroom flat in a shanty town, eating up much of her hard-earned income of 4,000 to 5,000 yuan.
