Perhaps you should try some spelling variations:
sach vay » sach va, sach hay, sach nay
cham cuu » cap cuu, chat cua
nang xa » nang x, lang xa, nang ma
va cham » va chat, va tham
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
cuu va » cuu van, cuu ve
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: te ((sach vay) OR (sach y)) nang xa hoi. lieu va cham cuu va hanh ((vi cua) OR (vai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach vay) or (sach y)) nang xa hoi. lieu va cham cuu va hanh ((vi cua) OR (vai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: te ((sach vay) or (sach y)) nang xa hoi. lieu va cham cuu va hanh ((vi cua) OR (vai cua)) te*.
