Perhaps you should try some spelling variations:
doan tien » doan thien, doanh tien, toan tien
trinh thi » trinh tai, dinh thi, trinh tin
dung cong » dung trong
trinh tu » trinh ky, trinh do
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thinh - hanh ((trinh thi) OR (trinh tu)) dung cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh ((trinh thi) OR (trinh tu)) dung cong tan toan cao*.
