Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
van hanh » van thanh, ban hanh, van anh
tu cach » tu cac
cach tu » cach thuc
lai cua » dai cua, hai cua, lai chau
duc van » duc va, duc tan, duc manh
va cham » va chat, va tham
cua tre » cua te, cuu tre, cua triet
tang ma » mang may, tang van
nang xa » nang x, lang xa, nang ma
va cam » va cac, va cao, va cai

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 cach tu ((nang xa) OR (tang ma)) hoi. hieu ((va cam) OR (va cham)) duc van hanh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tu ((nang xa) or (tang ma)) hoi. hieu ((va cam) OR (va cham)) duc van hanh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cach tu ((nang xa) or (tang ma)) hoi. hieu ((va cam) OR (va cham)) duc van hanh lai cua tre*.
