Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
luan dung » lan dung, luan dong, luan hung
cong tap » cuong tap, cong tan, tong tap
cong tac » cong ty
toan tap » toan 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: theo ((chua xang) OR (chieu tinh)) - hanh tang luan dung ((cong tap) OR (cong tac)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or (chieu tinh)) - hanh tang luan dung ((cong tap) OR (cong tac)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (chieu tinh)) - hanh tang luan dung ((cong tap) OR (cong tac)) toan tap*.
