Perhaps you should try some spelling variations:
hanh trang » thanh trung, hanh trinh, minh trang
chieu xanh » chieu sach, chieu sang, chieu tinh
dung cong » dung trong
chu xanh » chu manh, chua xang, chuc danh
qua dung » quang dung, su dung, qua song
cong van » cong vang, cong san, song van
van tuan » van quan, van ban, anh tuan
tuan cu » tuan tu, quan cua, tuan thu

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: theo ((chu xanh) OR (chieu xanh)) - ((hanh trang) OR (canh tranh)) qua dung cong van tuan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chieu xanh)) - ((hanh trang) OR (canh tranh)) qua dung cong van tuan cu~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chieu xanh)) - ((hanh trang) OR (canh tranh)) qua dung cong van tuan cu*.
