Perhaps you should try some spelling variations:
hieu nganh » vien nganh, hiem ngan, hieu manh
nhieu tang » chieu sang, hieu lang, nhiet nang
cua nhung » va nhung
anh tang » anh bang, anh dang, anh nang
tang cua » mang cua, hang cua, tang luan
nong tap » tong tap, nhung tap, cuong tap
nong tan » cong tan, nong dan, nong san
toan cau » toan cao, toan ban, toan tap

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 ((hieu nganh) OR (nhieu tang)) - anh tang cua nhung ((nong tap) OR (nong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu nganh) or (nhieu tang)) - anh tang cua nhung ((nong tap) OR (nong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu nganh) or (nhieu tang)) - anh tang cua nhung ((nong tap) OR (nong tan)) toan cau*.
