Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
hieu manh » chieu xanh, hieu nganh, hien hanh
tung tuan » trung tuan, hung tuan, quang tuan
tuan dung » tuan duong, tran dung, tan dung
dung cong » dung trong
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » 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 ((((hieu manh) OR (dieu hanh))) OR (chieu tinh)) - thanh tung tuan dung cong tac toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((hieu manh) OR (dieu hanh))) or (chieu tinh)) - thanh tung tuan dung cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((((hieu manh) OR (dieu hanh))) or (chieu tinh)) - thanh tung tuan dung cong tac toan cau*.
