Perhaps you should try some spelling variations:

tinh voi » trinh voi, tinh doi, binh voi
cau phuc » cau truc, chau phu, huu phuc
te sach » toc sach
voi cua » hoi cua, doi cua, moi cua
cua tre » cua te, cuu tre, cua triet
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
su sach » so sach, vu sach

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (su sach)) ky nang xa hoi. hieu va ((cam phuc) OR (cau phuc)) may tinh voi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) ky nang xa hoi. hieu va ((cam phuc) OR (cau phuc)) may tinh voi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) ky nang xa hoi. hieu va ((cam phuc) OR (cau phuc)) may tinh voi cua tre*".
