Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
hanh mang » nhanh mang, nhanh lang, thanh hang
dung cong » dung trong
chu manh » chu han, chu van, thu minh
cua dung » cua dang, cua dong, qua dung
cong anh » cong danh, dong anh, hong anh
anh van » anh va, thanh van, doanh van

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 ((chu manh) OR (ho manh)) - ((hanh trang) OR (hanh mang)) cua dung cong anh van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) OR (ho manh)) - ((hanh trang) or (hanh mang)) cua dung cong anh van ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) OR (ho manh)) - ((hanh trang) or (hanh mang)) cua dung cong anh van ban*.
