Perhaps you should try some spelling variations:
banh trang » hanh trang, ban trang, banh rang
hieu nganh » vien nganh, hiem ngan, hieu manh
hieu lang » chieu sang, hieu quang, nhieu tang
van dung » van dong, xay dung, tin dung
cong san » cong tac
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap
va dung » va duong, vat dung, va ung

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((hieu nganh) or (hieu lang)) - banh trang ((va dung) OR (van dung)) cong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((hieu nganh) OR (hieu lang)) - banh trang ((va dung) OR (van dung)) cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu nganh) or (hieu lang)) - banh trang ((va dung) OR (van dung)) cong san than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu nganh) or (hieu lang)) - banh trang ((va dung) OR (van dung)) cong san than cau*.
