Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh vai » hanh vi, hanh va, hanh tai
chat huu » pham huu
chat xuc » cam xuc, chao xu, chat cua
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
cuu tre » cua tre, cau tren, cau treo

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