Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
cuu tre » cua tre, cau tren, cau treo
truc va » thuc va, thuc vat, trung va
lang xa » lang ha, dang xay, lang van
van cam » van lam, van cau, van dam
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
tuc va » thuc va, tuc xa, duc va
vi cuu » vi luu, vinh cuu
tu sac » tu sach, tu cac, tu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang xa hoi. hieu ((van cam) or (van nam)) ((tuc va) OR (truc va)) thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ((van cam) OR (van nam)) ((tuc va) OR (truc va)) thanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((van cam) or (van nam)) ((tuc va) OR (truc va)) thanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ((van cam) or (van nam)) ((tuc va) OR (truc va)) thanh vi cuu tre*.
