English 找錯處

This sentence is not a full sentence. It is only a subject. 'who are veri kind' is the adjective of 'the guiders'. To make it be a complete sentence, please just omit 'who'.
i.e.
The guiders are very kind.

guiders應該是guides

冇ｇｕｉｄｅｒｓ　li個字,只有
GUIDE
嚮導,導遊;指導者
e.g.
A guide will show you round the Palace.
一位導遊將陪你們參觀宮殿。
I hope l can help you~
