Can you find out where others are at the border check?

Border inspection can find out where others are. Inquire through the official channels of China Customs. Every citizen who leaves the country is recorded in customs and border inspection. Through this system, citizens' entry and exit records in China can be mastered. But from country A to country B, from country C to country D, our system can't be found, because the border information all over the world is not shared online.
