enter by land with a car

I found some information on the internet. In order to bring your own vehicle into China, you need to get permission from certain Chinese departments. Then you need to apply for a temporary plate number and temporary driver license. In order to get it, you should meet the following requirements:
1. Proof of legal registration of your vehicle in your country
2. Approvement from Chinese customs saying "You can bring your vehicle into China"
3. Proof that shows your car has passed the safety check
4. already paid compulsory traffic accident insurance

The process is very completed.

Thank you for the information Jim,
any chance you can give me some contact of Chinese agency that can help me with all the paper?

Sorry, you may search online and find one yourself. I have no idea about this.

Thank You any way Jim, I try to ask just because I wrote to many agencies in China and none of them answered to me.
