Perhaps you should try some spelling variations:
sinh sach » sinh san, sang sach, sinh danh
hanh sang » anh sang, hanh mang, lanh sang
tong cong » trong cong, cong cong, dung cong
hanh san » thanh san, khach san, thanh son
cong van » cong vang, cong san, song van
va tong » va thong, va tuong, va trong
van tan » van tuan, van ban, van tai
tan cau » toan cau, van cau, tan ca

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: tien ((chinh sach) OR (sinh sach)) - ((hanh sang) OR (hanh san)) va tong cong van tan cau~.
• Adding a wildcard symbol may retrieve word variants: tien ((chinh sach) or (sinh sach)) - ((hanh sang) or (hanh san)) va tong cong van tan cau*.
