Thanks @Sxnan for the contribution!

I left 2 minor comments, please take a look in your free time.

BTW, IIUC the first commit is a refactor without any real change, right? If so, it's better to add [refactor] in the commit message. It's helpful for understand these commit, thanks~

[xintongsong]

LGTM.
