te sach » toc sach
ve cham » va cham, ve chat, vu cham
cua tre » cua te, cua triet, dua tren
va lang » va nang, hoa lang
cuu tre » cau tren, cau treo
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
cham o » cham soc
o hoi » co hoi, o hoc, o hai
x hoi » xa hoi, x ho, 5 hoi
o va » do va, so va, co va

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 ((x hoi) OR (o hoi)). hieu ve cham o va lang van ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((x hoi) OR (o hoi)). hieu ve cham o va lang van ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((x hoi) OR (o hoi)). hieu ve cham o va lang van ((cua tre) or (cuu tre))*".
