Perhaps you should try some spelling variations:
truc ban » thuc ban, truc dan, truc van
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
cuu tre » cua tre, cau tren, cau treo
tuc van » thuc van, truc van, tuc va
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
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 xa hoi. lieu va dau ((tuc van) or (truc ban)) ((hanh di) OR (hanh de)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang xa hoi. lieu va dau ((tuc van) OR (truc ban)) ((hanh di) OR (hanh de)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang xa hoi. lieu va dau ((tuc van) or (truc ban)) ((hanh di) OR (hanh de)) cuu tre*".
