Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thong cong » trong cong, tong cong, thong thong
hanh mang » nhanh mang, hanh trang, nhanh lang
mang luan » tang luan, hang luan, bang luan
hang cong » hang nong, bang cong, thanh cong
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - hanh mang luan ((((hang cong) OR (dang cong))) or (thong cong)) dan than cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - hanh mang luan ((((hang cong) OR (dang cong))) OR (thong cong)) dan than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh mang luan ((((hang cong) OR (dang cong))) or (thong cong)) dan than cao*".
