Love is magic

If you would be loved, love and be lovable.想被人爱，就必须去爱，或者使自己变得可爱。

From your Chinese, literal translation,

If you want to be loved, then you need to find love or to become lovable.

My interpretation:

If you want to be loved, go seek thy love and be lovable.

Love is magic

If you would be loved, love and be lovable.想被人爱，就必须去爱，或者使自己变得可爱。

Hello, this quote is nice and it would sound better this way:

- If you want to be loved

or

- If you would like to be loved
