tru nang » tra nang, tri nang, truc nano
cau xuc » cam xuc, cau luc, cau truc
cuu tre » cua tre, cau treo
xuc van » duc van, luc van, xuc ban
su sach » so sach, vu sach
tu nang » tu nong, tu nano, tu lang
van cau » van dau, van hau, van chat

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((tu nang) or (tru nang)) xa hoi. thien van cau xuc van thanh vi ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((tu nang) OR (tru nang)) xa hoi. thien van cau xuc van thanh vi ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((tu nang) or (tru nang)) xa hoi. thien van cau xuc van thanh vi ((cuu tre) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: su sach ((tu nang) or (tru nang)) xa hoi. thien van cau xuc van thanh vi ((cuu tre) OR (cau tren))*.
