Perhaps you should try some spelling variations:
hanh thang » nhanh thang, thanh thang, hanh trang
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
tieu xanh » tieu danh, chieu xanh, dieu hanh
thang va » hang va, trang va, thong va
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: "theo tieu xanh - hanh thang va ((nhung cong) OR (thong cong)) tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh thang va ((nhung cong) OR (thong cong)) tan toan cao*.
