Wuchuan city is a water town. Jianjiang, the largest river in western Guangdong, runs through the whole territory from north to south. Its tributaries, Meihuajiang, Meijiang and Sanchajiang, are distributed in the northeast with criss-crossing river networks. That river beach provides abundant feed for the growth of poultry and livestock. So Wuchuan produces more ducks and pigs. Duck and pork are not only supplied to the market, but also produced in large quantities in autumn and winter. Wuchuan people have long known how to cook bacon. The bacon they make is of high quality, delicious, unique in flavor and style. In the era of material scarcity, bacon has become the most delicious and nourishing food for Wuchuan people, and the best way to eat bacon is to cook sausage rice.

Ginger is a condiment in Wuchuan people's daily diet, and Wuchuan people can't live without ginger for a day. Jiang Ye called it "ginger", which is bright yellow and pleasing to the eye, well-proportioned and pleasing to the eye, and spicy and delicious. As early as the Zhou Dynasty, ginger had been cultivated artificially. Ginger is included in the cookbook in The Analects of Confucius and Lv Chunqiu. Xu Shen, a Confucian scholar in the Eastern Han Dynasty, called ginger a "damp-resistant dish" in Shuo Wen Jie Zi. Wang Anshi, a writer in the Song Dynasty, said in Zi Shuo that ginger "can resist all evils". Zhu, a master of Neo-Confucianism in the Southern Song Dynasty, said in The Analects that ginger can "get rid of evil spirits"; Li Shizhen, a medical scientist in the Ming Dynasty, praised ginger as "spicy but not fleshy, eliminating all evils". There are folk proverbs such as "ginger ginseng in October" and "it is better to drink ginseng chicken soup than to eat three slices of ginger early".

It is very scientific to eat ginger rice from winter solstice. The sun is located at the southernmost tip of the winter solstice, which is the shortest day and the longest night in the northern hemisphere. After the winter solstice, it enters the coldest stage of the year, which is often said as "nine cold days". What is most needed at this time is to keep out the cold and make up for it. Ginger is pungent and warm. It can stimulate appetite, stop vomiting, eliminate phlegm and relieve cough, and relieve exterior syndrome by sweating. The effect of keeping out the cold, bacon is a delicious nourishing food, so bacon-flavored ginger rice should be born and will last for a long time.

Every winter solstice, the streets and alleys of Wuchuan City are filled with all kinds of ginger just dug out of the ground, including more than ten kinds of ginger, such as sand ginger, spicy ginger, wind ginger, black ginger, yellow ginger, purple ginger, red ginger and white ginger, and all kinds of wild ginger that are rare at ordinary times also appear in the winter solstice market. This season coincides with the listing of all kinds of delicious bacon, sausage and preserved duck. On the solstice of winter, people will buy all kinds of ginger slices, bacon, sausages and ducks to cook delicious rice with ginger juice.
