5. Because the lunar calendar in China is a "Yin-Yang calendar", which is based on the movement of the sun and the moon, it can't fully reflect the solar cycle. However, China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is based entirely on the sun, so "24 solar terms" which reflect the solar cycle alone are added to the calendar as the criteria for determining leap months.
