Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
hoc thiet » hoc thieu, hoc thuyet, hoc hien
cua nhung » va nhung
ho nhiet » hoc nhiet, ho thiet, hoa thiet
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh 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: ((ho nhiet) OR (hoc thiet)) nang - ((hanh trinh) OR (thanh tung)) cua nhung cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho nhiet) OR (hoc thiet)) nang - ((hanh trinh) or (thanh tung)) cua nhung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho nhiet) OR (hoc thiet)) nang - ((hanh trinh) or (thanh tung)) cua nhung cong dan toan cao*.
