What is the recycling treasure process like?

I think the answer upstairs is very detailed, and the following is the original text upstairs:

The iPhone 7 was just released, so the iPhone 6 I used before was idle and well protected, so I thought about recycling it for some money, so I used recycling treasure. The process is relatively convenient. First, screen some mobile phone information on their official website, evaluate the mobile phone in the first round, then place an order if the price is no problem, and then mail the mobile phone to them. After they receive the mobile phone, they will quickly test it, and finally give you a recycling price. As long as the options you fill in in in official website are not much different from the ones actually tested, the general price will be the same, and then they will send you money after testing. The whole process has SMS to remind you of the progress.
