Perhaps you should try some spelling variations:
nhanh mang » nhanh lang, hanh mang, nhanh quang
hanh tung » thanh tung, manh tung, thanh trung
hanh dung » thanh dung, anh dung, hanh dong
tong cong » trong cong, cong cong, dung cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cua tong » cua cong, cua dong, cua nong
cong tap » cuong tap, cong tac, cong tan
tap van » tap va, tap vat, tap quan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((((hanh tung) OR (hanh dung))) OR (nhanh mang)) cua tong cong tap van ban~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((((hanh tung) or (hanh dung))) or (nhanh mang)) cua tong cong tap van ban*.
