Perhaps you should try some spelling variations:
ve triet » va trien, su triet
so sach » so sanh, bo sach, co sach
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
va tieu » van tieu, vay tieu, va dieu
sach ly » sach y, sach lo, sach ty
nang xa » nang x, lang xa, nang ma
ly nang » ky nang, ly hang, ly vang
ve nam » va nam, le nam, te nam
he nam » ha nam, nghe nam

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 ly nang xa hoi. hieu ((ve nam) OR (he nam)) thuc va hanh vi ((ve triet) or (va tieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ly nang xa hoi. hieu ((ve nam) OR (he nam)) thuc va hanh vi ((ve triet) OR (va tieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ly nang xa hoi. hieu ((ve nam) OR (he nam)) thuc va hanh vi ((ve triet) or (va tieu))".
• Adding a wildcard symbol may retrieve word variants: so sach ly nang xa hoi. hieu ((ve nam) OR (he nam)) thuc va hanh vi ((ve triet) or (va tieu))*.
