Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trang » thanh trung, canh tranh, hanh trinh
nhung cong » dung cong, thong cong, hang cong
trang cua » tranh cua, tang cua, trung cua
cua nhung » va nhung
viec bao » viec ban, viec va, viec so
viec lam » viec va

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 ((chieu tinh) OR (diep tinh)) - hanh trang cua nhung cong ((viec bao) OR (viec lam)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (diep tinh)) - hanh trang cua nhung cong ((viec bao) OR (viec lam)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (diep tinh)) - hanh trang cua nhung cong ((viec bao) OR (viec lam)) cao*.
