Perhaps you should try some spelling variations:
pham thuong » phan thuong, pham hong
chap thuong » chan thuong, phan thuong, han thuong
thieu xanh » chieu xanh, hieu manh, thien anh
thien danh » thien anh, thien dang, thien thanh
manh hung » anh huong
cong tap » cuong tap, cong tac, cong tan
tap toan » tap doan, tap quan, bai toan
toan cao » toan ban, toan tap

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: toc ((thieu xanh) OR (thien danh)) - manh hung ((chap thuong) OR (pham thuong)) cong tap toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) or (thien danh)) - manh hung ((chap thuong) OR (pham thuong)) cong tap toan cao~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) or (thien danh)) - manh hung ((chap thuong) OR (pham thuong)) cong tap toan cao*.
