van cam » van nam, van lam, van cau
hang di » hang doi, hang vi, hang dien
y nang » ly nang, v nang, may nang
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) OR (ky nang)) x hoi. thien van cam ((xuc va) or (luc va)) hang di cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (ky nang)) x hoi. thien van cam ((xuc va) OR (luc va)) hang di cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (ky nang)) x hoi. thien van cam ((xuc va) or (luc va)) hang di cua viet".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (ky nang)) x hoi. thien van cam ((xuc va) or (luc va)) hang di cua viet*.
