Perhaps you should try some spelling variations:
tinh hoi » trinh hoi, tinh hoc, tinh hai
hoi cua » hoi chuc
va tinh » may tinh
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va, hieu qua
hieu ve » hieu van
lang xa » dang xay, lang van
lang ha » long ha
lai ky » sai ky, dai ky
te lai » te tai, te bai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te lai ky ((lang xa) OR (lang ha)) hoi. ((hieu ve) or (hieu va)) am thuc va tinh hoi cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te lai ky ((lang xa) OR (lang ha)) hoi. ((hieu ve) OR (hieu va)) am thuc va tinh hoi cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te lai ky ((lang xa) OR (lang ha)) hoi. ((hieu ve) or (hieu va)) am thuc va tinh hoi cua vat".
• Adding a wildcard symbol may retrieve word variants: te lai ky ((lang xa) OR (lang ha)) hoi. ((hieu ve) or (hieu va)) am thuc va tinh hoi cua vat*.
