Perhaps you should try some spelling variations:
hieu manh » chieu xanh, hieu nganh, dieu hanh
chau tinh » cuu tinh, ha tinh, cua tinh
tran tuan » tran quang, tran thanh, tranh luan
tran xuan » tran quang, tran van
dung cong » dung trong
cong tap » cuong tap, cong tac, cong tan
tap quan » tac quan, hai quan
quan ban » quang ban, qua ban, quan van

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: ho ((hieu manh) OR (chau tinh)) - thanh ((tran tuan) OR (tran xuan)) dung cong tap quan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chau tinh)) - thanh ((tran tuan) OR (tran xuan)) dung cong tap quan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chau tinh)) - thanh ((tran tuan) OR (tran xuan)) dung cong tap quan ban*.
