Perhaps you should try some spelling variations:
chau triet » cau triet, cua triet, cau trieu
hanh lai » hanh lam, hanh tai, thanh lap
sach ty » sach y, sach tu, sach thu
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
va nam » ha nam, va nay
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach thieu)) nang xa hoi. hieu ((va nam) OR (van nam)) xuc va hanh lai chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach thieu)) nang xa hoi. hieu ((va nam) OR (van nam)) xuc va hanh lai chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach thieu)) nang xa hoi. hieu ((va nam) OR (van nam)) xuc va hanh lai chau triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach thieu)) nang xa hoi. hieu ((va nam) OR (van nam)) xuc va hanh lai chau triet*.
