Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung lang
chieu tinh » trieu tinh, lieu tinh, chau tinh
canh manh » lanh manh, canh tranh, cach mang
nhung don » nhung van, nhung bo
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
manh cua » doanh cua, ban cua
dan phan » doan phan, dan chan, van phan
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 - canh manh cua ((((nhung cong) OR (nhung don))) OR (dung cong)) dan phan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - canh manh cua ((((nhung cong) OR (nhung don))) or (dung cong)) dan phan dau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - canh manh cua ((((nhung cong) OR (nhung don))) or (dung cong)) dan phan dau*.
