Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
lanh tren » lang tren, lanh truyen, doanh tren
cac ban » cac dan, cac van, can ban
cuc ban » cua ban, cuu ban, duc ban
va cham » va chat, va tham
nang xa » lang xa, nang ma, mang xa
cua tre » cua te, cuu tre, cua triet
vi cua » vai 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: thuat lanh tren ((nang xa) OR (nang x)) hoi. lieu va cham ((cuc ban) OR (cac ban)) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh tren ((nang xa) OR (nang x)) hoi. lieu va cham ((cuc ban) or (cac ban)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: thuat lanh tren ((nang xa) OR (nang x)) hoi. lieu va cham ((cuc ban) or (cac ban)) hanh vi cua tre*.
