Perhaps you should try some spelling variations:
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
qua lap » quan lap, qua ap, qua la
xuc van » vuc van, xuc ban, thuc van
luc van » luoc van, luu van, luc va
duc van » duc va, duc tan, duc manh
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
vi cuu » vi luu, vinh cuu

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. hieu qua lap ((xuc van) or (((luc van) or (duc van)))) hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu qua lap ((xuc van) OR (((luc van) OR (duc van)))) hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu qua lap ((xuc van) or (((luc van) or (duc van)))) hanh vi cuu tre*.
