In the vast and varied landscape of China, the ancient Chinese have developed a unique and intricate system to predict and understand the weather. One of the most fascinating aspects of this system is the concept of Guyu, which is a traditional method of weather forecasting. Guyu, also known as the “twenty-four solar terms,” is a set of divisions of the year that were created based on the changes in the sun’s position and the natural phenomena observed in China. This article aims to provide a comprehensive English introduction to Guyu, focusing on its three stages and their significance in the traditional Chinese weather system.
Stage 1: The Beginning of Guyu
The first stage of Guyu begins with the first solar term, known as “Start of Spring” (Chūnjiāo). This term marks the beginning of spring and the transition from winter to summer. During this time, the days become longer, and the temperature gradually rises. The natural phenomena that characterize this stage include the blooming of flowers, the awakening of insects, and the gradual melting of snow.
The “Start of Spring” is a time of renewal and vitality, and it is closely associated with the Chinese New Year celebrations. It is a time when people traditionally plant crops and begin to prepare for the upcoming harvest. The ancient Chinese believed that the weather during this period would have a significant impact on the rest of the year, and therefore, it was of great importance to observe and predict the weather accurately.
Stage 2: The Progression of Guyu
The second stage of Guyu consists of the remaining solar terms, which are:
- Rise of the Dragon (Chūwǔ)
- Clear and Bright (Qīngmíng)
- Grain in Ear (Mǎiwèi)
- Grain in Ear Full (Mǎijiāo)
- Summer Solstice (Xiàzhì)
- Dog Days (Xiāoxiāo)
- Autumn Begins (Qiūfēng)
- Cold Dew (Lěngshuǐ)
- Hoard in the Barn (Shuǐsì)
- Heavy Snow (Dàxuě)
- Winter Solstice (Dōngzhì)
- End of Winter (Chūnjié)
Each of these terms is associated with specific weather patterns and natural phenomena. For example, “Rise of the Dragon” is characterized by warm and humid weather, while “Summer Solstice” is marked by the longest day of the year and the beginning of the summer heat. The progression of Guyu reflects the changing seasons and the natural cycles of the earth.
Stage 3: The Conclusion of Guyu
The third and final stage of Guyu concludes with the “End of Winter” solar term. This term signifies the end of the winter season and the beginning of spring. It is a time of transition, as the cold weather begins to subside, and the days start to get longer and warmer. The natural phenomena that characterize this stage include the blooming of flowers, the return of birds, and the awakening of insects.
The “End of Winter” is a time of hope and renewal, as it marks the beginning of a new year and the opportunity for new beginnings. It is a time when people traditionally celebrate the New Year and make resolutions for the year ahead. The weather during this period is also of great importance, as it will set the tone for the rest of the year.
Conclusion
Guyu is a fascinating aspect of China’s traditional weather system, and its three stages reflect the changing seasons and the natural cycles of the earth. By understanding the significance of each stage and the natural phenomena associated with them, we can gain a deeper appreciation for the intricate relationship between humans and the natural world. Whether you are a student of Chinese culture or simply curious about the history of weather forecasting, Guyu offers a rich and rewarding exploration of the past.
