Perhaps you should try some spelling variations:
hieu nganh » vien nganh, hiem ngan, hieu manh
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
cua trong » cua truong, cua trung, qua trong
cong dang » cong dan, cong dung, cong danh
tran chau » tranh chap, tran huu

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: toc ((hieu nganh) OR (chieu xanh)) - hanh tranh cua trong ((cong dang) OR (cong dong)) tran chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((hieu nganh) or (chieu xanh)) - hanh tranh cua trong ((cong dang) OR (cong dong)) tran chau~".
• Adding a wildcard symbol may retrieve word variants: toc ((hieu nganh) or (chieu xanh)) - hanh tranh cua trong ((cong dang) OR (cong dong)) tran chau*.
