hung manh » hung anh, tung manh, duong manh
chu nang » chuc nang, chua nang, chu bang
cuu nang » chuc nang, cam nang, cuu van
toan cau » toan cao, toan ban, toan tap

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chu nang) or (cuu nang)) - hanh tang va nhung ((hung manh) OR (nhung manh)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu nang) OR (cuu nang)) - hanh tang va nhung ((hung manh) OR (nhung manh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu nang) or (cuu nang)) - hanh tang va nhung ((hung manh) OR (nhung manh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chu nang) or (cuu nang)) - hanh tang va nhung ((hung manh) OR (nhung manh)) toan cau*.
