The city where the physical examination of the college entrance examination needs naked examination

Naked check is not the traditional sense of letting people accept nude inspection, but the airport for security checks equipped with a full-body scanning equipment, on the strict inspection. This full-body scanning equipment can show the human body's "naked" outline, and provide detailed photos of suspicious parts. The U.S. authorities also hope to promote full-body scanning security technology in airports across the United States.

The college entrance examination is generally referred to as the national unified examination for enrollment in colleges and universities.

The national unified examination for admission to colleges and universities, or "gaokao" for short, is a selective examination for qualified high school graduates or candidates with equivalent qualifications.
