Perhaps you should try some spelling variations:

chat xuc » chat huu, cam xuc, chao xu
va hanh » van hanh, va thanh, va danh
cau luc » cau truc, cau phuc
sach ky » sac ky, sach y, sach kem
nang xa » nang x, lang xa, nang ma
sach ty » sach y, sach tu, sach thu
cuc tre » duc tre, cua tre, cuu tre

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((chat xuc) or (cau luc)) va hanh tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((chat xuc) OR (cau luc)) va hanh tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((chat xuc) or (cau luc)) va hanh tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sach ty)) nang xa hoi. hieu qua ((chat xuc) or (cau luc)) va hanh tai cuc tre*.
