Perhaps you should try some spelling variations:
trung trinh » trang trinh, trung tinh, trung thanh
hanh trung » thanh trung, hanh trang, manh trung
trinh bang » trinh bong, tinh bang, trinh ban
chua xang » chua nang, chuc nang, chu bang
bang cong » dang cong, bang song, hang cong
chu xanh » chu manh, chieu xanh, chuc danh
cong tac » cong ty
than sao » than so, than vao, thanh san
toan cao » toan ban, toan tap

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 xanh) OR (chua xang)) - hanh trung trinh bang cong tac ((than sao) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chua xang)) - hanh trung trinh bang cong tac ((than sao) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chua xang)) - hanh trung trinh bang cong tac ((than sao) or (toan cao))*.
