Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
su triet » su viet, su tien, ve triet
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
sac ky » sai ky
va cam » va cham, va cac, va cai
va cao » va cac, va co, va dao

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) or (cac ky)) nang xa hoi. hieu ((va cam) or (va cao)) thuc va hanh lai su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (cac ky)) nang xa hoi. hieu ((va cam) OR (va cao)) thuc va hanh lai su triet.
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) or (cac ky)) nang xa hoi. hieu ((va cam) or (va cao)) thuc va hanh lai su triet*.
