Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, le thanh
su sach » so sach, vu sach
ty nang » ky nang, ty xang, ly nang
ty hang » ly hang, ty xang, thi hang
hieu ve » hieu va, hieu van
va tinh » may tinh
va cua » va chua, via cua, ca cua
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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) or (ty hang)) xa hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty nang) OR (ty hang)) xa hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty nang) or (ty hang)) xa hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) va cua te".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty nang) or (ty hang)) xa hoi. hieu ve cam xuc ((va thanh) OR (va tinh)) va cua te*.
