Perhaps you should try some spelling variations:
hieu vien » hieu hien, hieu viec, thieu nien
bach xuc » bach tuoc, bach xuan, bach hue
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
ky sang » ky dang, ky tang, duy sang
va hanh » van hanh, va thanh, va danh
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
ma hoi » mai hoi, xa hoi, me hoi
xuc va » duc va, tuc va, luc va

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: te sach ((ky sang) OR (ky nang)) ((ma hoi) OR (ma hoa)). hieu vien bach xuc va hanh vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky sang) or (ky nang)) ((ma hoi) OR (ma hoa)). hieu vien bach xuc va hanh vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky sang) or (ky nang)) ((ma hoi) OR (ma hoa)). hieu vien bach xuc va hanh vai cuu tre*.
