Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
hanh tang » anh tang, hanh mang, hanh tung
dung cong » dung trong
thanh lap » thanh san, phan lap, thanh hai
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
qua dung » quang dung, su dung, qua song
cong dan » cong san, cong tan, huong dan
than cap » khan cap, thanh cac, than cua

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 - ((hanh tang) OR (hanh trang)) qua dung cong dan ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh tang) or (hanh trang)) qua dung cong dan ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh tang) or (hanh trang)) qua dung cong dan ((than cap) OR (thanh lap))*.
