Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
truong cao » truong dai
truong dao » truong dai, truong bo
lang cong » dang cong, bang cong, hang cong
thanh lap » thanh san, phan lap, thanh hai
ho chieu » theo chieu, hoc thieu, doi chieu
cong ban » cong bang, cong san, cong tan
than cap » khan cap, thanh cac, than cua

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: ho chieu tinh - manh ((truong cao) OR (truong dao)) lang cong ban ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - manh ((truong cao) or (truong dao)) lang cong ban ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - manh ((truong cao) or (truong dao)) lang cong ban ((than cap) OR (thanh lap))*.
