Perhaps you should try some spelling variations:
phai sinh » thai binh, pham minh, nhan sinh
phau sinh » pham minh, nhan sinh, phau benh
hanh mang » nhanh mang, hanh trang, nhanh lang
mang luan » tang luan, hang luan, bang luan
luan dung » lan dung, luan dong, luan hung
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
tran cau » tran chau, toan cau, ran cau

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 ((phai sinh) OR (phau sinh)) - hanh mang luan dung ((cong tan) OR (cong tac)) tran cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((phai sinh) OR (phau sinh)) - hanh mang luan dung ((cong tan) or (cong tac)) tran cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((phai sinh) OR (phau sinh)) - hanh mang luan dung ((cong tan) or (cong tac)) tran cau*.
