Perhaps you should try some spelling variations:
chua xang » chuc nang, chu bang, chua dong
chua nang » chuc nang, kha nang, cuu nang
hanh tang » hanh trang, anh tang, hanh mang
tang luan » dung luan
luan doan » luan hoan, quan doan, luat doanh
dan tai » dan thi, han tai, ban tai
van tai » von tai, van tuan

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 (chua nang)) - hanh tang luan doan phuong ((dan tai) OR (van tai)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or (chua nang)) - hanh tang luan doan phuong ((dan tai) OR (van tai)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (chua nang)) - hanh tang luan doan phuong ((dan tai) OR (van tai)) cao*.
