Perhaps you should try some spelling variations:
khi xanh » khia canh, thi anh, thi oanh
thi hanh » thi thanh
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban
cong van » cong vang, cong san, song van
van tuan » van quan, van ban, anh tuan
tuan cau » toan cau, quan cau, tuan cu

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

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