Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, pham duc
luu tre » luu tru, cuu tre, luy tre
danh di » danh du, xanh di, danh dien
va danh » va dinh, va dan, va hanh
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
lang ha » long ha
sai ky » sac ky
di luu » vi luu
su sai » su tai, su hai, su dai

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sai ky ((nang xa) or (lang ha)) hoi. hieu va ((cham xuc) OR (cham soc)) va danh di luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky ((nang xa) OR (lang ha)) hoi. hieu va ((cham xuc) OR (cham soc)) va danh di luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky ((nang xa) or (lang ha)) hoi. hieu va ((cham xuc) OR (cham soc)) va danh di luu tre".
• Adding a wildcard symbol may retrieve word variants: su sai ky ((nang xa) or (lang ha)) hoi. hieu va ((cham xuc) OR (cham soc)) va danh di luu tre*.
