Introduction to wedding candy:

Wedding candy was used as one of the six-color or twelve-color gifts in the wedding ceremony of the husband’s family in old-time weddings. When the bride gets on the car (sedanan), When the bride and groom enter the bridal chamber, they must sprinkle wedding candies so that everyone can share the sweetness and beauty together. Wedding candies in traditional weddings are divided into four varieties, called "four-color wedding candies", including rock candy, winter melon candy, orange candy and longan, symbolizing the four distinct seasons, sweetness and growing old together.

Related legends:

At the wedding, people have to offer sweets to the bride to eat. In fact, it was not wedding candy that was given out at first, but red eggs. So why do you need red eggs when you get married? There is a legend:

In the Three Kingdoms, there is a story about "Liu Bei recruiting a bride". "Liu Bei recruiting a bride" was the strategy of Zhou Yu, the governor of Soochow. Zhou Yu wanted to use the method of pretending to recruit a bride but actually detaining Liu Bei as a hostage, and asked Liu Bei to return Jingzhou. Unexpectedly, this strategy was discovered by Liu Bei's military advisor Zhuge Liang. Among the "good tips" Zhuge Liang prepared for Liu Bei was the "red egg offering strategy".

When Liu Bei went to Soochow to find his bride, Zhuge Liang asked someone to boil a lot of red eggs and bring them with him. As soon as they arrived in Soochow, officials, big and small, both inside and outside the palace, gave soldiers and soldiers to everyone they met, saying that this was a royal wedding etiquette.

There was no such custom in Soochow, so I thought it was very new, so I spread it from one person to another, so that every household knew that the princess of Soochow, Sun Shangxiang, and the emperor's uncle Liu Bei were about to get married. Liu Bei was proud of his uncle's red eggs. Those who did not get the red eggs rushed to Liu Bei's residence to ask for them.

For a time, the whole Soochow was in an uproar. As a result, he had to do it for real, Liu Bei married the princess of Soochow, and Zhou Yu ended up "losing both his wife and his army". Since then, the traditional wedding custom in Jiangnan has included the content of giving red wedding eggs, and over time, it has evolved into giving wedding candies.
