hang hoi » hang hoa, hang hai, hang doi
cua tre » cua te, cuu tre, dua tren
va hang » van hang, va nang, va lang
te sach » toc sach
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
y nang » ky nang, ly nang, may nang
xuc va » duc va, tuc va, luc va
v nang » va nang, vu nang, van nang

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 (v nang)) xa hoi. hieu ve chat xuc va hang hoi ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu ve chat xuc va hang hoi ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) or (v nang)) xa hoi. hieu ve chat xuc va hang hoi ((cua tre) OR (cua triet))*".
