Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh tai » thanh tai, hang tai, han tai
va hanh » van hanh, va thanh, va danh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, dua tren
cam luc » cam xuc
cau luc » cau truc, cau phuc
te sai » te tai, te bai, te lai
sai ky » sac ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky lang xa hoi. hieu va ((cam luc) or (cau luc)) va hanh tai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky lang xa hoi. hieu va ((cam luc) OR (cau luc)) va hanh tai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky lang xa hoi. hieu va ((cam luc) or (cau luc)) va hanh tai ((cua tre) OR (cua triet))*".
