Perhaps you should try some spelling variations:
hanh tri » thanh tri, hanh tai, hanh trinh
va hanh » van hanh, va thanh, va danh
van lam » van nam
van cam » van nam, van cau, van dam
lang xa » lang ha, dang xay, lang van
sach ty » sach y, sach tu, sach thu
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sac ky) or (sach ty)) lang xa hoi. hieu ((van cam) OR (van lam)) luc va hanh tri cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sac ky) OR (sach ty)) lang xa hoi. hieu ((van cam) OR (van lam)) luc va hanh tri cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sac ky) or (sach ty)) lang xa hoi. hieu ((van cam) OR (van lam)) luc va hanh tri cua te".
• Adding a wildcard symbol may retrieve word variants: toc ((sac ky) or (sach ty)) lang xa hoi. hieu ((van cam) OR (van lam)) luc va hanh tri cua te*.
