Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung lang
chau tinh » cuu tinh, ha tinh, cua tinh
tranh cua » doanh cua, manh cua
nhung don » nhung van, nhung bo
dung cong » dung trong
doi chau » doi chieu, gioi chau, hoi chu
toan cau » toan cao, toan ban, toan tap

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi chau tinh - canh tranh cua ((((nhung cong) OR (nhung don))) or (dung cong)) tinh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chau tinh - canh tranh cua ((((nhung cong) OR (nhung don))) OR (dung cong)) tinh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chau tinh - canh tranh cua ((((nhung cong) OR (nhung don))) or (dung cong)) tinh toan cau*".
