Perhaps you should try some spelling variations:
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
cham tu » pham tu, cam tu, chai tu
vai cua » dai cua, hai cua, lai cua
sac ky » cac ky, sai ky
tu gia » tu giao, tu giac, tu giay
vi cua » di 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 ky) OR (sac ky)) nang xa hoi. hieu ve cham tu gia thanh ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cham tu gia thanh ((vi cua) or (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cham tu gia thanh ((vi cua) or (vai cua)) tre*.
