Perhaps you should try some spelling variations:
vai cua » dai cua, hai cua, lai cua
va danh » va dinh, va dan, va hanh
cac duc » cac du, cao duc, cac dac
hieu ve » hieu va, hieu van
mai hoi » mai khoi, dai hoi, lai hoi
sac ky » cac ky, sai ky
ve cac » va cac, vien cac
ma hoi » xa hoi, ma hoa, me hoi
di cua » dai cua, doi cua, de cua
tu sac » tu sach, tu cac, tu san

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 sac ky nang ((ma hoi) OR (mai hoi)). hieu ve cac duc va danh ((di cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((ma hoi) OR (mai hoi)). hieu ve cac duc va danh ((di cua) or (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((ma hoi) OR (mai hoi)). hieu ve cac duc va danh ((di cua) or (vai cua)) tre*.
