Perhaps you should try some spelling variations:
thanh tung » thanh cong
han thuong » phan thuong, lan thuong, pham thuong
cong hach » cong sach, cong thanh, cong khanh
hach toan » thanh toan, manh toan
thi kiem » thi kim, thi lien, thi hien
toan ban » van ban
ho lieu » so lieu, co lieu, ho kieu

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 lieu) OR (thi kiem)) tinh - thanh tung ((han thuong) OR (hang thuong)) cong hach toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) or (thi kiem)) tinh - thanh tung ((han thuong) OR (hang thuong)) cong hach toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) or (thi kiem)) tinh - thanh tung ((han thuong) OR (hang thuong)) cong hach toan ban*.
