Perhaps you should try some spelling variations:
tru nang » tra nang, tri nang, truc nano
hieu van » hieu va, thien van, lieu va
te sach » toc sach
tu nang » tu nong, tu nano, tu lang
van cam » van nam, van lam, van cau
xuc van » duc van, xuc ban, thuc van
luc van » luoc van, luu van, duc van
cuu tre » cua tre, cau tren, cau treo
vi cuu » vi luu, vinh cuu

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)) xa hoi. hieu van cam ((xuc van) OR (luc van)) hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tru nang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) or (tru nang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) hanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu nang) or (tru nang)) xa hoi. hieu van cam ((xuc van) OR (luc van)) hanh vi cuu tre*.
