The Chinese characters "妤菸" are pronounced as yú yān. In English pronunciation, there is no exact equivalent for these two characters. However, for reference, "yú" could be somewhat similar to the sound "you" but with a softer "u" sound. "yān" is similar to the sound "yen" but with a softer "e" sound. These are just approximations as Chinese pronunciation is unique and not exactly the same as English sounds. ????
