Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
nhung cong » dung cong, thong cong, nhung don
hang cong » dang cong, hang nong, bang cong
than phan » thanh phan, toan phan, thanh pham
ho chieu » theo chieu, hoc thieu, doi chieu
phan dau » phan tu, hang dau

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 chieu tinh - thanh ((truong cua) OR (truong cao)) ((nhung cong) OR (hang cong)) than phan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh ((truong cua) or (truong cao)) ((nhung cong) OR (hang cong)) than phan dau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh ((truong cua) or (truong cao)) ((nhung cong) OR (hang cong)) than phan dau*.
