Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
va thanh » gia thanh, ban thanh, va tinh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » hieu qua
cam luc » cau luc
cuc tre » duc tre, cua tre, cuu tre
tu sac » tu sach, tu cac, tu 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: tu sac ky lang xa hoi. ((hieu va) or (lieu va)) ((cam luc) OR (cam xuc)) va thanh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. ((hieu va) OR (lieu va)) ((cam luc) OR (cam xuc)) va thanh tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. ((hieu va) or (lieu va)) ((cam luc) OR (cam xuc)) va thanh tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. ((hieu va) or (lieu va)) ((cam luc) OR (cam xuc)) va thanh tai cuc tre*.
