Is the solar term time affected by geographical location? Is it the same all over the country?

Yes, the twenty-four solar terms were arranged in ancient times according to the climatic conditions of the Yellow River basin, and certainly not suitable for the whole country. The north-south span of China is too large. The 24 solar terms accurately reflect the characteristics of natural forces in a year, but they cannot represent the climate change in China. There are also differences in climate between the United States and China. Solar terms can respond to time, but have a low guiding role in climate prediction.
