danh sai » dung sai, danh bat, danh dau
thuc va » thuc vat, thuc dan, thuc day
danh va » doanh va, hanh va, anh va
tu sach » thu sach, su sach, te sach
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho
va am » va lam, va cam

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang x hoi. hieu ((ve am) OR (va am)) thuc va ((danh va) or (danh sai)) cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu ((ve am) OR (va am)) thuc va ((danh va) OR (danh sai)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu ((ve am) OR (va am)) thuc va ((danh va) or (danh sai)) cua viet".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu ((ve am) OR (va am)) thuc va ((danh va) or (danh sai)) cua viet*.
