During the Eastern Han Dynasty, the "Shennong Bencao Jing" recorded the medicinal value of Pueraria root and orange peel. About 900 years ago, Nangelu first founded the traditional production technology of "Orange Brew" and started the origin of ancient Pueraria root powder. The Pueraria root powder it made had pure aroma, warm and cool, and had a sweet taste in the mouth.

The "orange brew" production technique created by the ancestors of Nangelu was cumbersome and difficult to replicate, and the teaching still followed the traditional method of word-of-mouth and understanding. At present, the trend of machine processing is prevalent, and the process is reduced secretly, eager for quick success and instant benefits, regardless of quality. However, Nangelu always adheres to the ancient method, does not save things and does not reduce their strength, just to present the authentic taste of Nangelu.

In the mid-1990s, the planting of Pueraria root added potatoes, cassava and other starch, occupied the market at a low price, and was named "wild Pueraria root powder". Many people who were keen on Pueraria root powder were greatly disappointed after purchasing: "There is no Pueraria root powder now. Ge Xiang doesn't have the taste of the past..." Nan Ge Lu always adheres to the ancestral teachings: "Although no one sees piety, he will know it if he is determined." He has never used planting Pueraria root, but only made authentic ancient Pueraria root powder with authentic traditional skills. . In 2019, Mr. Gao Fahong, the 42nd generation descendant of Nangelu, was named the inheritor of the intangible cultural heritage of "Galaxanthin Making Technique". To this day, the Nangelu Ge Noodle Family still follows the ancestral teachings and only makes authentic and traditional skills of orange-made ancient Pueraria root powder.
