Camellia oleifera noodles were probably originated in Henan.
The specific location should be Wuzhi in Jiaozuo, Henan.
Nowadays, Camellia oleifera noodles are available in major regions of our country, including the Northeast.
There is a record in the history book "Notes from Yu":
According to legend, in the first year of Yongzheng in the Qing Dynasty, Emperor Yinzhen visited Wuzhi to supervise the work in order to control floods in the Yellow River. Build a dam. In order to gain the favor of their masters, local dignitaries sent people around to collect delicacies from the mountains and seas for the emperor. At that time, in order to please the emperor, Wu Shilu, the magistrate of Wuzhi County, sent one of the most famous chefs to painstakingly prepare a refined and rare food called "oil tea". The emperor was very happy after using it. Wu Shilu was flattered and opened an oil tea house as ordered. In addition to the royal family, he also entertained officials. Since then, Wuzhi Camellia oleifera has become famous. Some vendors who were engaged in street stalls also changed their careers and learned to make camellia oleifera. Some are hawking on their shoulders, some are setting up shops, and some are traveling around. Post terminals in various prefectures and counties competed with each other to set up terminals, and business was booming. According to legend, the family named Wang made the best oil tea at that time.
Wuzhi oil tea tastes fragrant but not greasy, and is delicious. It is made of fried noodles and contains sesame oil, peanuts, sesame seeds, walnut kernels, etc. Because it is a milky thin juice that looks like strong tea, it is named "oil tea". After several evolutions, the camellia oleifera changed from thin to thickened to a "porridge" shape, and tea was used instead of rice. Some large and medium-sized cities have also set up "Wuzhi Camellia Oil Tea Snack Bars". The state has also specially selected two oil tea masters to make oil tea in the Great Hall of the People to serve the chief ministers and foreign guests.
Wuzhi Camellia oleifera is not only famous in China, but also spread to Western Europe, Southeast Asia and other places. In the 1930s, students studying in England and France, in order to work-study, carried an oil teapot (a mobile tea-selling device, several times larger than an ordinary teapot, and wrapped themselves in quilts to prevent heat dissipation), and hawked it on the streets of London and Paris. It was welcomed by the local people. To this day, some Chinese consulates in Paris still serve camellia oleifera as the best soup.
