Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
chuc dang » chuc nang, chuc danh, thuoc dang
dang cong » dung cong
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan ban » van 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: ho ((hieu manh) OR (chieu tinh)) - ((hanh tang) OR (hanh mang)) chuc dang cong van toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu tinh)) - ((hanh tang) OR (hanh mang)) chuc dang cong van toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu tinh)) - ((hanh tang) OR (hanh mang)) chuc dang cong van toan ban*.
