Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
tru nang » tra nang, tri nang, thi nang
te sach » toc sach
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
hieu vo » hieu voi, hieu va, hieu ve
cuu tre » cua tre, cau tren, cau treo
tu nang » tu nong, tu nano, tu lang
co tuc » co thuc, co tu, co toc
tuc va » thuc va, truc va, tuc xa
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: te sach ((((tu nang) OR (tru nang))) or (truc nano)) x hoi. hieu vo co tuc va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((tu nang) OR (tru nang))) OR (truc nano)) x hoi. hieu vo co tuc va hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((tu nang) OR (tru nang))) or (truc nano)) x hoi. hieu vo co tuc va hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((((tu nang) OR (tru nang))) or (truc nano)) x hoi. hieu vo co tuc va hanh vai cuu tre*.
