Perhaps you should try some spelling variations:

chat vuc » chat huu, chat cua, chat hoc
chat xuc » chat huu, cam xuc, chao xu
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
sach ky » sac ky, sach y, sach ty
cho hoc » co hoc, khoa hoc
hieu va » lieu va, hieu qua
vi cua » vai cua, di cua

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 ky nang cho hoc. hieu va ((((chat vuc) OR (chat xuc))) or (chat va)) van hanh vi cua cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang cho hoc. hieu va ((((chat vuc) OR (chat xuc))) OR (chat va)) van hanh vi cua cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang cho hoc. hieu va ((((chat vuc) OR (chat xuc))) or (chat va)) van hanh vi cua cac*".
