Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
doi chieu » doc hieu, doi chi, ho chieu
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan 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 thieu) OR (doi chieu)) xanh - hanh ((trinh quan) OR (trinh han)) nhung cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chieu)) xanh - hanh ((trinh quan) OR (trinh han)) nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chieu)) xanh - hanh ((trinh quan) OR (trinh han)) nhung cong tan toan tap*.
