Perhaps you should try some spelling variations:
cau phuc » cau truc, chau phu, huu phuc
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
phuc va » phuc vu, thuc va, chuc va
va hanh » van hanh, va thanh, va danh
vai cua » hai cua, lai cua, bai cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. ((hieu ve) OR (lieu va)) cau phuc va hanh ((vai cua) OR (dai cua)) viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. ((hieu ve) or (lieu va)) cau phuc va hanh ((vai cua) OR (dai cua)) viet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. ((hieu ve) or (lieu va)) cau phuc va hanh ((vai cua) OR (dai cua)) viet*.
