Perhaps you should try some spelling variations:
manh hai » lanh hai, minh hai, thanh hai
cac luc » cau luc, coc luc, cac nuoc
hai cua » thai cua, dai cua, hoi cua
va manh » van manh, va danh, va hanh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va
sach ky » sach y, sach ty, sach kem
luc va » duc va, tuc va, loc va
cua te » cua tu
sac ky » cac ky, sai ky

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 (sac ky)) nang xa hoi. ((hieu va) OR (hieu qua)) cac luc va manh hai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) or (hieu qua)) cac luc va manh hai cua te~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang xa hoi. ((hieu va) or (hieu qua)) cac luc va manh hai cua te*.
