Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc chieu » hoc thieu, hoc hien, hoc dieu
truong va » truong dai, truong cao, truong dao
ho chieu » theo chieu, hoc thieu, doi chieu
trung va » trang va, trung ha, trung tam
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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: ((hoc chieu) OR (ho chieu)) xanh - manh ((trung va) OR (truong va)) nhung cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) xanh - manh ((trung va) or (truong va)) nhung cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (ho chieu)) xanh - manh ((trung va) or (truong va)) nhung cong dan than cau*.
