What is the word light beard light? Is this spoken English? I can't seem to find it!

Light is the pinyin of the Chinese character "light". If you put it before the English word "beard", it means "no beard" or "no hair on your mouth" Maybe someone in China invented authentic English.

As for "beard", English has different words in different parts:

1, beard: the hair on the chin, cheeks and throat, that is, "beard"

2, moustache: long hair on the lips, that is, "moustache"

Beard: the hair on the cheeks and chin, that is, "beard"
