Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
va cham » va chat, va tham
tai cua » thai cua, tai cuc, tri cua
va hanh » van hanh, va thanh, va danh
lang xa » lang ha, dang xay, lang van
luc va » duc va, tuc va, loc va
va cam » va cac, va cao, va cai
sac ky » cac ky
cua tu » cua tuc, cua su, cua cu

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 (sai ky)) lang xa hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (sai ky)) lang xa hoi. hieu ((va cam) OR (va cham)) luc va hanh tai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) lang xa hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) lang xa hoi. hieu ((va cam) or (va cham)) luc va hanh tai cua tu*.
