Perhaps you should try some spelling variations:
hieu quan » lieu quan, thien quan, lien quan
cua triet » cua viet, su triet, va triet
cach tru » cach tu, cac tru, cach thuc
van anh » van thanh, tuan anh, van minh
luc van » luoc van, luu van, duc van
cam luc » cam xuc, cau luc
su cach » su sach, tu cach, su cac
nang xa » lang xa, nang ma, mang xa
anh di » danh di, xanh di, anh d
di cua » dai cua, doi cua, de cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su cach tru ((nang xa) OR (nang x)) hoi. ((hieu qua) OR (hieu quan)) cam luc van anh di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cach tru ((nang xa) OR (nang x)) hoi. ((hieu qua) or (hieu quan)) cam luc van anh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: su cach tru ((nang xa) OR (nang x)) hoi. ((hieu qua) or (hieu quan)) cam luc van anh di cua triet*.
