The Chinese character "到" (dào) primarily means "to arrive" or "to reach." It is commonly used to indicate the destination of a movement or the completion of an action. For example, in the phrase "我到家了" (wǒ dào jiā le), it translates to "I have arrived home." In addition to its use in physical movement, "到" can also express the attainment of a goal or a point in time. For instance, "我到达了目标" (wǒ dào dá le mù biāo) means "I have reached the goal." This versatility makes "到" an essential character in everyday Chinese communication.
