Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
sach ty » sach tu, sach thu, xach tay
hang xa » hoang xa, hang va, hang ca
hieu va » lieu va, hieu qua
va pham » van pham, va phat, va phap
chuc va » thuc va, thuc vat
va hanh » van hanh, va thanh, va danh
vi cua » vai cua
di cua » dai cua, doi cua, de 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) OR (sach y)) hang xa hoi. hieu va pham chuc va hanh ((vi cua) OR (di cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach y)) hang xa hoi. hieu va pham chuc va hanh ((vi cua) OR (di cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach y)) hang xa hoi. hieu va pham chuc va hanh ((vi cua) OR (di cua)) te*.
