Beauty salons can repair hair salons, and there is also a place for professional eyebrow trimming (there seems to be one under Chengkang Bridge), and the bus at the cosmetics counter can also repair it for you free (if you look like you are shopping there).

Because your hair grows faster, I suggest a professional to trim it for you (if you are satisfied), and buy a safe eyebrow trimmer (available from Watsons, not expensive) to trim it yourself according to the approximate eyebrow shape he gave you.
