Today's briefs were called "cow noses" in ancient China. Biography of Sima Xiangru in Historical Records: "If you are close to the ambassador of Qiongtong (Table), you can sell a car and ride it, buy a wine house to drink, and let it be a stove. Zhao Wei said, "Make a three-foot piece of cloth look like a calf's nose. Call this man shameless. Today, the bronze seal said it was new, and so on. "Mixed with Bao Yong, the washing machine is in the city. Zhuo Wangsun was ashamed to say, "Zhuo Wangsun must give Wen Jun one hundred children, millions of money, their wedding clothes and belongings. Wen Jun bought a farmhouse in his hometown in Chengdu and was very rich. "
We can know from the annotation of "calf nose" in Historical Records that "calf nose fold" has two openings that can pass through the feet, like calf nose. Moreover, it only uses three feet of cloth (the ancient ruler is much shorter than today's), and it is estimated that it only covers the front without covering the buttocks (modern Japanese still have such pants), which is more "transparent" and "exposed" than today's briefs, and "bikini" is "what a good thing!" Of course, the "calf nose" is only for men to wear, and the hot climate in Sichuan is more suitable. Later, the back of the "calf nose" was sewn on, which became an out-and-out "briefs"!
