te sach » toc sach
ty nang » ty hang, ly nang, ty nong
hieu ve » hieu va, hieu van
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc 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 ((((ty nang) OR (ty xang))) or (ky nang)) xa hoi. hieu ve cam xuc va tinh viet cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((ty nang) OR (ty xang))) OR (ky nang)) xa hoi. hieu ve cam xuc va tinh viet cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((ty nang) OR (ty xang))) or (ky nang)) xa hoi. hieu ve cam xuc va tinh viet cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((((ty nang) OR (ty xang))) or (ky nang)) xa hoi. hieu ve cam xuc va tinh viet cua tre*.
