等于

The Chinese word 等于 (děngyú) is composed of two characters: 等 (děng) and 于 (yú). 等 means "equal" or "same", while 于 is a preposition that means "to" or "at". Together, 等于 means "equal to" or "the same as".The character 等 is derived from the oracle bone script, which is the earliest known form of Chinese writing. In the oracle bone script, 等 is depicted as a person standing on a platform, with two hands raised in the air. This image represents the idea of equality, as the person is standing at the same level as the platform.The character 于 is also derived from the oracle bone script. In the oracle bone script, 于 is depicted as a person kneeling down, with their hands outstretched. This image represents the idea of submission or obedience, as the person is bowing down to a higher authority.When the characters 等 and 于 are combined, they create the word 等于, which means "equal to" or "the same as". This word is used in a variety of contexts, such as mathematical equations, comparisons, and analogies. For example, the equation 2 + 2 = 4 can be written as 二加二等于四 (èr jiā èr děngyú sì), which means "two plus two equals four".
