"Looking at Gu Xiu on June 6th" is a folk proverb in China, which literally means "Looking at the ears of rice on June 6th in the lunar calendar". In rural China, June 6th is the eighth day of the twenty-four solar terms, and it is the time when rice is about to heading. The moral behind this proverb is farmers' expectations for crop growth and harvest.

On the sixth day of the sixth lunar month, farmers will observe the growth of crops to see if they start heading and flowering, which is an important stage in the growth process of crops and a key period to determine whether crops can be harvested.
