Perhaps you should try some spelling variations:
chat huu » pham huu
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
va danh » va dinh, va dan, va hanh
y nang » ky nang, ly nang, v nang
huu va » cuu va, tuu va
vi cua » vai cua
di cua » doi cua, de cua, do 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: te sach y nang xa hoi. hieu ve chat huu va danh ((vi cua) OR (((di cua) OR (dai cua)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ve chat huu va danh ((vi cua) or (((di cua) OR (dai cua)))) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ve chat huu va danh ((vi cua) or (((di cua) OR (dai cua)))) tre*.
