Perhaps you should try some spelling variations:
nhanh hai » nhanh thai, thanh hai, nhanh ha
va triet » va thiet, va trien, ve triet
thuc dan » thuc hanh, hoc dan, thuc vat
hanh hai » thanh hai, hang hai, hanh tai
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
hieu he » hiem he, hieu le, hieu hien
nang xa » nang x, lang xa, nang ma

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang xa hoi. ((hieu he) OR (hieu ve)) am thuc dan ((hanh hai) or (nhanh hai)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. ((hieu he) OR (hieu ve)) am thuc dan ((hanh hai) OR (nhanh hai)) va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. ((hieu he) OR (hieu ve)) am thuc dan ((hanh hai) or (nhanh hai)) va triet*".
