What is the trick of those people on Douyin chasing mortgaged cars?

TikTok’s trick for chasing mortgaged cars is to look at the vehicle file information, which will show the mortgage time. If it is more than three months, it is considered a safe car. As long as it is not locked, it can be used normally, even if it is seized. It does not affect the use. As long as there are no problems with the mortgage procedures and the creditor's rights are clear and there are no disputes between three or four parties, the time for signing the transfer agreement is not a problem, so I still recommend not to buy it.
