The Chinese word 周期 (zhōuqī) for "cycle" or "period" is composed of two characters: 周 (zhōu) and 期 (qī). 周 originally meant "complete" or "thorough", and was often used to refer to a full cycle of time, such as a day or a year. 期, on the other hand, originally meant "to wait for" or "to expect", and was often used to refer to a specific point in time. When combined, 周期 (zhōuqī) took on the meaning of a "complete period of time" or a "cycle".The word 周期 (zhōuqī) has been used in Chinese for centuries to refer to a variety of different cycles, including the cycle of the seasons, the cycle of the moon, and the cycle of life and death. It is also used to refer to more abstract cycles, such as the cycle of history or the cycle of economic growth and decline.The word 周期 (zhōuqī) is a versatile and important word in Chinese, and it is essential for HSK learners to understand its meaning and usage.
