The modern Chinese Symbol for mother mu still looks similar to the original Oracle Bone Inscriptions. (Mother is normally referred to as mu3 qing1)
What we can see from the pictogram is this: two dots representing the breast of a mature female, two hands outstretched as though working and the woman is kneeling down in a submissive position (supposedly infront of her husband). I just find this pictogram fascinating for its descriptive content.
Here are some expressions with the symbol for mother:
mu3 qing1 = mother
mu3 qing1 jie2 = mother's day
mu3 ai4 = mother's love
mu3 lao2 hu3 = tigress, referring to a shrew
mu3 xiao4 = old school, Alma Mater
mu3 yu3 = mother tongue
