According to the ancient book "Insult in Hanshu", Emperor Huan of the Eastern Han Dynasty wanted to establish Liang Nvying, the daughter of the general Liang Shang, as the queen. Before their marriage, Emperor Huan of Han specially sent Wu Mi, a female official, to the residence of General Liang. When Ai Wu entered the door, he first observed Liang Nvying's walking posture, and felt that his figure was symmetrical, graceful and impeccable. Then, Ai Wu invited Liang Nvying into the boudoir and asked Liang Nvying to take off her clothes, and then carefully examined all parts of her body.

Liang Nvying, the daughter of a wealthy aristocratic family, refused to comply. Wu Ke had to show "the sword above" and threatened: "This is the imperial edict of the emperor, and it is the rule after the emperor's election. Whoever wants to be a queen has to take off all his clothes and let me examine them carefully. " Looking forward to becoming a queen, Liang Nvying hardly went into the boudoir for examination.

Wu Mi, a female official, first examined the shape and texture of Liang Nvying's breasts, and then sniffed her body for body odor. Then, she carefully examined the shape and depth of the navel, her shoulder width, waist circumference, the elasticity of her hips, her skin color, length, the curvature of her legs, and the colors of her fingers and toes. Finally, seriously ask about the medical history.

After the physical examination showed no abnormality, Ai Wu checked Liang Nvying's facial features and hair. After repeated tests, he finally asked Liang Nvying to say "Long live" three times to check how his vocal cords sounded.
