2. Predict climate change: Solar terms can help people predict future climate change, so as to make preparations in advance. For example, solar terms such as beginning of spring, Changchun, beginning of autumn and beginning of winter mark the change of seasons. People can make preparations for increasing or decreasing clothes and planting crops in advance according to the arrival of these solar terms.

3. Inheriting cultural knowledge: Solar terms are an important part of China traditional culture.
