Perhaps you should try some spelling variations:
tdanh trung » thanh trung, thanh tung, dang trung
danh trung » dang trung, dinh trung, manh trung
chau tinh » cuu tinh, ha tinh, cua tinh
cua nhung » va nhung
cong van » cong vang, cong san, song van
cong tac » cong ty
toan cao » toan ban, toan tap
ho chau » ha chau, ho chu, o chau

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 chau tinh - ((danh trung) OR (tdanh trung)) cua nhung ((cong van) OR (cong tac)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - ((danh trung) or (tdanh trung)) cua nhung ((cong van) or (cong tac)) toan cao*.
