nhung cong » dung cong, thong cong, hang cong
tieu tinh » trieu tinh, tieu trinh, lieu tinh
manh tung » manh hung, thanh tung
cua nhung » va nhung
hoc tieu » hoc thieu, hoc dieu, hoc sieu
cong tap » cuong tap, cong tac, cong tan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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: hoc tieu tinh - ((manh tung) OR (thanh trung)) cua nhung cong tap ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc tieu tinh - ((manh tung) or (thanh trung)) cua nhung cong tap ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc tieu tinh - ((manh tung) or (thanh trung)) cua nhung cong tap ((toan cau) OR (toan ban))*.
