hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
su sach » so sach, vu sach
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
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: ((tu sach) OR (su sach)) tham nang x hoi. hieu ve cam xuc va ((han tai) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) tham nang x hoi. hieu ve cam xuc va ((han tai) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) tham nang x hoi. hieu ve cam xuc va ((han tai) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) tham nang x hoi. hieu ve cam xuc va ((han tai) or (hanh va)) cua tre*.
