Analysis:

There is a high-pillar flea market with second-hand furniture and electrical appliances. Used computers is on the third floor of Taihe Electronic City. The second-hand mobile phone is on the first floor of Taihe. Second-hand equipment has Shijiazhuang second-hand network. When buying second-hand things, I don't think we should pay first, but two days in advance. If the other person is not at ease, check with him every day.
