Perhaps you should try some spelling variations:
hanh thai » nhanh thai, hinh thai, hanh tai
cuu tre » cau tren, cau treo
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, cua triet, dua tren
cam luc » cam xuc
cau luc » cau truc, cau phuc
te sac » te sach, te cac, te san
sac ky » cac ky, sai 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 sac ky lang xa hoi. hieu va ((cam luc) or (cau luc)) va hanh thai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. hieu va ((cam luc) OR (cau luc)) va hanh thai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. hieu va ((cam luc) or (cau luc)) va hanh thai ((cua tre) OR (cuu tre))*".
