HANGZHOU, Aug. 3 (Xinhua) -- At the height of summer, with the arrival of Major Heat, the final solar term of the season, American Emma Chen follows an ancient Chinese way of staying cool: drinking unfermented Pu"er tea.

　　For the volunteer guide at Hangzhou"s Liangzhu Museum in east China, this is more than a seasonal habit. Through her years of experience in China, she has learned to follow the rhythm of the 24 solar terms, choosing seasonal foods and teas in the process, and has gained a better understanding of the Chinese belief in living in harmony with nature.

　　The solar terms people have followed for thousands of years constitute an organizing principle and rule for agrarian societies, Chen said. In the Liangzhu period 5,000 years ago, people lived in an agrarian civilization and they required a solar system to better manage their rice cultivation.

　　Fluent in Chinese, Chen studied Asian Studies as an undergraduate in the United States before settling in China. Now in her fifth year as a guide at Liangzhu Museum, Chen has immersed herself in the archaeology of China"s Neolithic cultures, helping visitors discover the wisdom of the Liangzhu civilization through stories of its sophisticated social structure, farming practices and exquisite jade artifacts.
