Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu tinh » trieu tinh, lieu tinh, chau tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
cap dung » ap dung, chan dung, cach dung
cao dung » cao dang, cao dong, cao ung
dan van » dang van, doan van, tan van
dao van » do van, dang van

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu tinh - thanh trung ((cap dung) OR (cao dung)) cong ((dan van) or (dao van)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - thanh trung ((cap dung) OR (cao dung)) cong ((dan van) OR (dao van)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - thanh trung ((cap dung) OR (cao dung)) cong ((dan van) or (dao van)) ban*".
