Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc va
vu sach » vu bach, su sach, vu khach
sach ty » sach y, sach tu, sach thu
hanh di » hanh vi, hanh de, hang di
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
tuc va » thuc va, truc va, duc va
va dau » va dao
di cuu » di cau, di cua, dinh cuu

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

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