Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
trung cap » truong cao, trung tam
cap nhung » cam nhung, vap nhung, dap nhung
doc hieu » toc thieu, hoc hien
van than » van thanh, van thang, van tuan
dan chan » dan gian, dan ca, van chat

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: ((doc hieu) OR (hoc thieu)) xanh - thanh trung cap nhung cong ((van than) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (hoc thieu)) xanh - thanh trung cap nhung cong ((van than) or (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) OR (hoc thieu)) xanh - thanh trung cap nhung cong ((van than) or (dan chan)) cau*.
