Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thuc ban » thuoc ban, thuc dan, thu ban
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, lai cua
di cua » dai cua, doi cua, de cua
so sai » so dai, so hai, do sai
sai ky » sac ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao

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 sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) thuc ban thanh ((vai cua) OR (di cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) thuc ban thanh ((vai cua) or (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: so sai ky nang xa hoi. hieu ((ve cam) OR (va cam)) thuc ban thanh ((vai cua) or (di cua)) tre*.
