Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
hoc thieu » toc thieu, hoc hien
doanh cua » doanh luan
dang cong » dung cong
manh cua » ban cua
toan cao » toan ban, toan tap
doi chi » doi khi

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 chi)) xanh - canh ((manh cua) OR (doanh cua)) dang cong thanh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) xanh - canh ((manh cua) OR (doanh cua)) dang cong thanh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) xanh - canh ((manh cua) OR (doanh cua)) dang cong thanh toan cao*.
