Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
nang xa » nang x, lang xa, nang ma
thu ban » thu hang
vai cua » dai cua, hai cua, lai cua
so sac » so sach, so dac
sac ky » cac ky, sai ky
ve nam » he nam, va nam, te nam
le nam » ly nam, he nam, le na
di cua » dai cua, doi cua, de 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: so sac ky nang xa hoi. hieu ((ve nam) OR (le nam)) thu ban thanh ((vai cua) OR (di cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky nang xa hoi. hieu ((ve nam) OR (le nam)) thu ban thanh ((vai cua) or (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: so sac ky nang xa hoi. hieu ((ve nam) OR (le nam)) thu ban thanh ((vai cua) or (di cua)) tre*.
