Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
vai cua » dai cua, hai cua, lai cua
thuc va » thuc vat, thuc dan
nang ha » nang hai, nang han, nang hoa
hieu ve » hieu va, hieu van
ve nam » he nam, va nam, le nam
san ky » sang ky, van ky, dan ky
ha hoi » hoa hoi, ha noi, xa hoi
vi cua » di cua
tu san » thu san, tu ban, tu can

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 san ky nang ha hoi. hieu ve nam ((thuc va) OR (thuc day)) hanh ((vi cua) OR (vai cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang ha hoi. hieu ve nam ((thuc va) OR (thuc day)) hanh ((vi cua) or (vai cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang ha hoi. hieu ve nam ((thuc va) OR (thuc day)) hanh ((vi cua) or (vai cua)) triet*.
