Perhaps you should try some spelling variations:
tranh chuc » tranh chua, tranh cua, trang phuc
hanh tranh » canh tranh, hanh trinh, hanh trang
thien anh » thien danh, tien anh, thien thanh
chuc dang » chuc nang, chuc danh, thuoc dang
dang cong » dung cong
cong dan » cong san, cong tan, huong dan
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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 ((dieu hanh) OR (thien anh)) - hanh tranh chuc dang cong dan ((phan cau) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((dieu hanh) or (thien anh)) - hanh tranh chuc dang cong dan ((phan cau) OR (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((dieu hanh) or (thien anh)) - hanh tranh chuc dang cong dan ((phan cau) OR (phan cac))*.
