Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
lang xa » lang ha, dang xay, lang van
lai cuu » lai cua, lai chau, lai cuoc
va hanh » van hanh, va thanh, va danh
cao luc » bao luc, cao duc, cao suc
hieu va » lieu va, hieu qua
tu sach » thu sach, su sach, tu cach
nang xa » nang x, nang ma, mang xa
te sach » toc sach
cuu tre » cua tre, cau tren, cau treo
va cao » va cac, va co, va dao
luc va » duc va, tuc va, loc va

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) OR (te sach)) y ((nang xa) OR (lang xa)) hoi. hieu va cao luc va hanh lai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y ((nang xa) or (lang xa)) hoi. hieu va cao luc va hanh lai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) y ((nang xa) or (lang xa)) hoi. hieu va cao luc va hanh lai cuu tre*.
