The Proverbs of Summer Solstice
This folk song vividly describes the changes in weather from hot summer to cool autumn.
Due to the vastness of China and global warming, this folk song may not be suitable anymore. But weather becoming hotter and hotter after Summer Solstice is still the trend.
Many couplets about Summer Solstice are natural in words but exquisite. One famous couplet goes, "If there are thunders in Summer Solstice, the summer following will be very hot; if there is no rain in Double-ninth Festival, weather in the winter following will be sunny."
There is another couplet that goes, "Tomb-sweeping Day is for Kaoliang and Grain in Bud for Grain; sesame in Grain in Ear and beans in Summer Solstice."
