Perhaps you should try some spelling variations:
hinh sinh » tinh sinh, hinh dinh, hinh kinh
dong cong » duong cong, dung cong, dang cong
theo chu » theo chieu, cho chu, chao chu
chu bang » thu bang, chuc nang, chu quang
sinh cua » manh cua, dinh cuu, sinh va
cua dong » chua dong, cua cong, cua dang
dan than » dan chan, ban than, van than

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: theo chu bang - hinh sinh cua dong cong ((dan than) OR (van ban)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chu bang - hinh sinh cua dong cong ((dan than) or (van ban)) cau*.
