I suggest you don't cherish these luxurious dresses,

I suggest you cherish your youth.

When the flowers are suitable for folding, we should fold them quickly.

Don't wait for the flowers to wither before breaking an empty branch.

translate

Don't cherish wealth, cherish youth. Just like blooming flowers, we should pick them in time. If you don't pick it in time, you can only break the branches when the spring flowers fall. If you like someone, just tell TA directly, and don't wait until you miss it.
