Perhaps you should try some spelling variations:

nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
xuc ban » duc ban, cuc ban, quoc ban
ban anh » ban hanh, ban banh, ban danh
hai cua » thai cua, dai cua, lai cua
hoi cua » hoi chuc
sai ky » sac ky
va cam » va cham, va cac, va cao

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 kem) or (sai ky)) nang xa hoi. hieu va cam xuc ban anh ((hai cua) OR (hoi cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sai ky)) nang xa hoi. hieu va cam xuc ban anh ((hai cua) OR (hoi cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sai ky)) nang xa hoi. hieu va cam xuc ban anh ((hai cua) OR (hoi cua)) tre*".
