Perhaps you should try some spelling variations:
ban hanh » ban hang
lang ha » long ha
cua tre » cua te, cua triet, dua tren
xuc ban » duc ban, cuc ban, quoc ban
cuu tre » cau tren, cau treo
lang xa » dang xay, lang van
san ky » sang ky, van ky, dan ky
va cam » va cham, va cac, va cao
tu san » thu san, tu ban, tu can

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

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