There is a saying in Guilin for drinking "oil tea": "One cup is bitter, two cups are pinch (dialect, meaning astringent) and three or four cups are good oil tea." This is to remind you to taste it slowly and appreciate it well. "Oleifera tea" has the functions of dispelling cold and dampness, refreshing and filling the stomach. The humidity in northern Guangxi is high and there are many miners. Drinking "oil tea" has become a eating habit of the local people, and it is also a way for them to entertain guests. The guests sit around the table, and the host uses a small stove to cook "Wenjun" When it's on the stove, it's operated in public, one cup after another, it's quite flavorful. Nowadays, "oil tea" has spread like wildfire and spreads to several places in Guangxi. It is favored by people and has several flavors, such as "chicken shredded oil tea", "shredded pork oil tea", etc.
