Liu Haichang will be cut in two or three months, which is natural.
Not straight anymore
in other words
If you don't cut it, the effect is still there
It won't be straight once you cut it.
I know it first hand.
I didn't cut it to save trouble and keep the effect.
Then cut it when it really doesn't work.
Unfortunately, it soon bent.
You can cut it and then pull it.
hope this helps
