There are two kinds of inches, one is inch (the British unit of length) and the other is inch (the traditional unit of length in China). In daily life, 8 inches mostly refers to the size of photos, or the diameter of round objects such as cakes and pizzas. In ancient Chinese characters, inch consists of "you" representing the hand and "one" representing things. The original meaning refers to the one-inch long part from the palm to the wrist, that is, the "inch mouth", and the extension refers to the length unit with the inch mouth as the degree. Because inch is a small unit of measurement, it is also used to describe tiny or extremely short.
