Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh vai » hanh vi, hanh va, hanh tai
lang xa » lang ha, dang xay, lang van
song xa » song cua
nam xuc » nam xua, nam thuc, nam duoc
va hanh » van hanh, va thanh, va danh
vai cuu » vai cua
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 cac ky ((lang xa) or (song xa)) hoi. hieu van ((nam xuc) OR (cam xuc)) va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((lang xa) OR (song xa)) hoi. hieu van ((nam xuc) OR (cam xuc)) va hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((lang xa) or (song xa)) hoi. hieu van ((nam xuc) OR (cam xuc)) va hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((lang xa) or (song xa)) hoi. hieu van ((nam xuc) OR (cam xuc)) va hanh vai cuu tre*.
