What does it mean to believe in many things?

Pinduoduo merchants sell second-hand goods as new products on the platform of Pinduoduo, which have obvious signs of use and no logo, and belong to three-no products. According to the law, when they buy second-hand goods as new products, they can ask for a refund of one and a compensation of three. Charging a new machine is to sell the machine that has been used for a few days as a new one. The mobile phone is still in use, but its appearance is better protected. ? It means that it is completely comparable to the new one and not cheaper than the new one. For example, when the iPhone is plugged into the computer or the serial number is queried, it is obvious that the activation date can be identified. These parameters cannot be hidden. For Android, there is no way to look at the activation date, only the appearance, so the new meaning just means that the appearance is similar to the new one. Chargers are different from refurbished machines. Refurbishment is to use the mobile phone for a long time, and replace all the broken parts inside and outside. Some are original, and some are part of the cottage.
