Eat sugar cane backwards.

Eating sugar cane backwards means that the more you eat, the sweeter it is, which describes that people's situation is getting better and better.

The story of Gu Kaizhi eating sugarcane comes from Shi Shuo Xin Yu. Gu Kaizhi was the most famous painter in Jin Dynasty. Gu Kaizhi loves sugar cane. Every time he eats sugar cane, he starts with the head of sugar cane and slowly eats it. This is the opposite of what most people eat. Someone asked him why he ate like this, and Gu Kaizhi replied, "Only by eating like this can he get better!" "Better" here means "more and more delicious".

The growth characteristics of sugarcane are from short plants to tall plants, so there is a saying that the longer the unearthed sugarcane is, the higher it is, so people often use sugarcane to pray for a good omen at sacrifices and traditional weddings, hoping that everything in life will get better and better. Because the sugar in sugarcane is stored in the roots of underground stems, the closer the sugarcane head is to the ground, the higher the sweetness, so it is getting better and better to describe people's situation with "eating sugarcane upside down".

Sugarcane cultivation in China can be traced back to the Zhou Dynasty. According to Eight Fujian Verticals, China started planting sugarcane in Zhou Pingwang in the fifth year (766 BC), but it was called "Zhejiang" at that time.

Putian used to be a famous hometown of sugarcane, and the annual output of Mulan Sugar Factory and Putian Sugar Factory in Putian accounted for half of Fujian Province. People have a soft spot for sugar cane, and there is a special folk custom: newlyweds, shortly after marriage, will hold a "son-in-law" activity, invite their son-in-law to their homes, treat them carefully, and entertain relatives and friends.

When you send your son-in-law home, you must wrap a pair of sugar cane with red rope according to the custom, and then let your daughter and son-in-law take it home, which means that the future will be as sweet as sugar cane.
