Perhaps you should try some spelling variations:
hanh truong » hanh trong, anh truong, manh truong
truong cong » trong cong, truong dong, truong long
truong cao » truong dai
cao truong » cac truong, cho truong, cau truong
hiem ngan » kim ngan, viem gan
cong dan » cong san, cong tan, huong dan
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac
bi tinh » vi tinh

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 ((hiem ngan) OR (bi tinh)) - hanh truong cao truong cong dan ((than cau) OR (than cap))~.
• Adding a wildcard symbol may retrieve word variants: ho ((hiem ngan) or (bi tinh)) - hanh truong cao truong cong dan ((than cau) or (than cap))*.
