1,3 句押韵（it, lit; heart, apart) ， 2，4 句押韵(me, key; for, door).

My mother's heart has so much pearl in it,
 She did so much before the world knew me.
 Her love for me grew into a tree, lit (lit 写在这行为了押韵）
 Up by a flame, blazing bright with a key.

The key unlocked my baby, loveless heart.
 It taught me to pity and to feel for.
 Holding on to my key, never apart,
 Always together, joined by open doors.
 
In the neighborhood, strolling down the lane,
 Hands in hand, she showed me the good and bad.
 Like Tai Chi, black and white, friends aren't the same.
 Her words engraved in my mind, I was glad.
