The traditional Chinese lunar calendar divides the year into 24 solar terms. Major Heat, (Chinese: 大暑), the 12th solar term of the year, begins this year on July 22 and ends August 6.

During Major Heat, most parts of China enter the hottest season of the year.

In China, the 24 solar terms were created thousands of years ago to guide agricultural production. But solar term culture is still useful today to guide people's lives through special foods, cultural ceremonies and even healthy living tips that correspond with each term.

The following are 7 things you should know about Major Heat.

During Major Heat, the sunshine, high temperatures, and heavy rainfall are good for agricultural crops. But like Minor Heat, many natural calamities such as floods, droughts and typhoons also happen during Major Heat. Therefore, it's important to harvest and plant in time to avoid setbacks caused by natural disasters.

Sending the Major Heat ship

Sending the Major Heat ship is a folk tradition spanning hundreds of years in Taizhou, Zhejiang province.

The ship is filled with various animals for sacrifice such as pigs, sheep, chicken, fish, and shrimps. More than 50 fish ermen take turns carrying the ship as they march through the streets. Drums are played and fireworks are lit. Both sides of the street are filled with people praying for blessings.

After a series of ceremonies, the ship is finally carried to the wharf. Then, the ship is pulled out of the fishing port and burned at sea. People carry out this ritual to pray for good harvests and health.
