Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
thuc va » thuc vat, thuc dan
tai cuu » tai cuc, tai buu, tai cua
dan tai » van tai, dan thi, han tai
cuu tre » cua tre, cau tren, cau treo
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sang ky » sang kyo, dang ky, tang ky
va nay » va ngay, va cay
san ky » van ky, dan ky, ban ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc ((san ky) OR (sang ky)) lang xa hoi. hieu va nay ((thuc va) or (thuc day)) dan tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((san ky) OR (sang ky)) lang xa hoi. hieu va nay ((thuc va) OR (thuc day)) dan tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((san ky) OR (sang ky)) lang xa hoi. hieu va nay ((thuc va) or (thuc day)) dan tai cuu tre*".
