Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, nhung don
canh manh » lanh manh, canh tranh, cach mang
hang cong » dang cong, hang nong, bang cong
hach toan » thanh toan, manh toan
ho chieu » theo chieu, hoc thieu, doi chieu
thi hieu » thi chieu, thi hien, thi dieu
manh cua » doanh cua, ban cua
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: ((ho chieu) OR (thi hieu)) tinh - canh manh cua ((nhung cong) OR (hang cong)) hach toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi hieu)) tinh - canh manh cua ((nhung cong) OR (hang cong)) hach toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi hieu)) tinh - canh manh cua ((nhung cong) OR (hang cong)) hach toan tap*.
