Perhaps you should try some spelling variations:
su sach » so sach, vu sach
ly nang » ky nang, ly hang, ly vang
tuc van » thuc van, truc van, duc van
hanh de » hanh ve, hanh kem
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, v nang, may nang
va dau » va dao
tuc va » thuc va, truc va, tuc xa
de cuu » de cua

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 ((y nang) or (ly nang)) xa hoi. lieu va dau ((tuc van) OR (tuc va)) hanh de cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ly nang)) xa hoi. lieu va dau ((tuc van) OR (tuc va)) hanh de cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (ly nang)) xa hoi. lieu va dau ((tuc van) OR (tuc va)) hanh de cuu tre*".
