Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
su sach » so sach, vu sach
hanh di » hanh vi, hanh de, hang di
tuc van » truc van, tuc va, duc van
cuu tre » cua tre, cau tren, cau treo
ty hang » ly hang, ty xang, thi hang
ty nang » ky nang, ty xang, ly nang
di cuu » di cau, di cua, dinh cuu
va dau » va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ty nang) OR (ty hang)) xa hoi. lieu va dau ((tuc van) or (thuc van)) hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty hang)) xa hoi. lieu va dau ((tuc van) OR (thuc van)) hanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) OR (ty hang)) xa hoi. lieu va dau ((tuc van) or (thuc van)) hanh di cuu tre*".
