Perhaps you should try some spelling variations:
sach ky » sach ty, sach kem, sach hay
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
va hanh » van hanh, va thanh, va danh
ca tren » cau tren, cu tren, la tren
sac ky » cac ky, sai ky
vi ca » vit ca, li ca, va ca

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) OR (sach y))) OR (sac ky)) nang xa hoi. hieu ve cham tu va hanh vi ca tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach y))) or (sac ky)) nang xa hoi. hieu ve cham tu va hanh vi ca tren~".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ky) OR (sach y))) or (sac ky)) nang xa hoi. hieu ve cham tu va hanh vi ca tren*.
