Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cua tinh
cua nhung » va nhung
hoc chau » hoc chat, moc chau, hoc cau
hanh han » hanh nhan, hanh phan, anh han
hanh san » thanh san, khach san, thanh son
cong san » cong tac
toan tap » toan ban
toan cao » toan ban

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: hoc chau tinh - ((hanh han) OR (hanh san)) cua nhung cong san ((toan tap) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: hoc chau tinh - ((hanh han) or (hanh san)) cua nhung cong san ((toan tap) or (toan cao))*.
