Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh tai » thanh hai, thanh toan, doanh tai
nang lai » nang tai, mang lai, nang cai
thuc xay » thuc day, tuc xay, thuat xay
hanh tai » hang tai, han tai, hinh tai
lai hoi » dai hoi, lai hoa, lai roi
thuc xa » tuc xa, thuc va, thuc ha
tu van » tu va
va nay » va ngay, va cay

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky nang lai hoi. lieu va nay ((thuc xa) or (thuc xay)) ((hanh tai) OR (thanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang lai hoi. lieu va nay ((thuc xa) OR (thuc xay)) ((hanh tai) OR (thanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang lai hoi. lieu va nay ((thuc xa) or (thuc xay)) ((hanh tai) OR (thanh tai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang lai hoi. lieu va nay ((thuc xa) or (thuc xay)) ((hanh tai) OR (thanh tai)) cua triet*.
