According to historical records, after eating the dumplings, the Soviet Red Army played tricks on the Northeastern sister-in-law.

According to historical records, the Soviet Red Army was interested in two things in the Northeast: eating dumplings and playing with their sisters-in-law.

This is the origin of the Soviet proverb "Nothing is more delicious than dumplings, and no more fun than sister-in-law."

Dumplings, also known as dumplings, formerly known as "Jiao Er", are an ancient traditional pasta in China. They originated from Wancheng in the Central Plains and have a history of more than 1,800 years.

Dumplings are deeply loved by the Chinese people and are a must-eat during the Spring Festival in most parts of northern China. In many provinces and cities, there is also the custom of eating dumplings during the Winter Solstice.

Dumplings were invented by Zhang Zhongjing, the medical sage of Nanyang in the Eastern Han Dynasty. Its history has gone through a long process. Zhang Zilie gave a good explanation in the late Ming Dynasty: "Shui Jiao Er, Duan Cheng-style food, Tang Zhongluo Wan, or powder

Jiao, the northerners pronounce Jiao as Jiao, and call it Dumpling Bait, so it is called Jiaoer. When making dumplings, people often put Jin Ruyi, sugar, peanuts, dates, chestnuts, etc. into the stuffing.

Those who eat as they wish and eat sweets will have sweeter days in the coming year; those who eat peanuts will be healthy and live longer; those who eat dates and chestnuts will have children early.

In some areas, when eating dumplings, people also eat some non-staple food to show good luck.

For example, eating tofu symbolizes the happiness of the whole family; eating persimmons symbolizes everything goes well; eating three fresh vegetables symbolizes the prosperity of the three Yangs.

In some places in the south, during the Chinese New Year, eggs are beaten, heated, wrapped in a wrapper and filled with meat, called egg dumplings.
