Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang
chu manh » ho manh, chu han, chu van
cua dong » chua dong, cua cong, cua nong
cua dang » cua cong, cua ban
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) OR (chua xang)) - hanh tang ((cua dong) OR (cua dang)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) OR (chua xang)) - hanh tang ((cua dong) OR (cua dang)) cong dan toan cau*.
