Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh luan » trinh luan, trinh luat, doanh luan
thong cong » trong cong, thong thong, phong chong
hang cong » dang cong, hang nong, bang cong
tong cong » trong cong, cong cong, dung cong
chi xanh » chi anh, chi danh, chi hanh
van tuan » van quan, van ban, anh tuan
tuan ban » tuan bang, toan ban, luan ban
doi chi » doi khi

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: doi chi xanh - hanh tranh luan ((hang cong) OR (((thong cong) OR (tong cong)))) van tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - hanh tranh luan ((hang cong) or (((thong cong) OR (tong cong)))) van tuan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh tranh luan ((hang cong) or (((thong cong) OR (tong cong)))) van tuan ban*.
