Perhaps you should try some spelling variations:
tuong cua » truong cua, huong cua, luong cua
thong cua » thong quan, thong tu, huong cua
dang cong » dung cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cao » toan ban, toan tap

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 - manh ((tuong cua) OR (thong cua)) dang cong tac toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - manh ((tuong cua) or (thong cua)) dang cong tac toan cao*.
