thanh ve » hanh ve, thanh vien, thanh van
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
va chat » van chat, va phat, hoa chat
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang xa hoi. hieu ((va chat) OR (cao chat)) xuc van ((thanh ve) or (thanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((va chat) OR (cao chat)) xuc van ((thanh ve) OR (thanh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((va chat) OR (cao chat)) xuc van ((thanh ve) or (thanh va)) cua tre*".
