Perhaps you should try some spelling variations:
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
xuc ban » duc ban, cuc ban, quoc ban
hang do » hang doi, dang do, hang di
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
hang d » hang di, hang du, hang dau

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 xa hoi. lieu va cam xuc ban ((hang d) OR (hang do)) ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. lieu va cam xuc ban ((hang d) OR (hang do)) ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. lieu va cam xuc ban ((hang d) OR (hang do)) ((cua tre) or (cuu tre))*".
