2. Why is grapefruit also called Wendan? ? According to legend, "Wendan" is the stage name of an actress surnamed Wen in southern Fujian. She not only plays well, but also likes planting pomelo trees. Every pomelo tree will produce very beautiful pomelo. In ancient books, grapefruit is described as "white and fragrant, charming and attractive", which is as imaginative as the names of actresses and beautiful women.
