Perhaps you should try some spelling variations:
cach viet » bach viet, anh viet, danh viet
tinh tri » dinh tri, minh tri, chinh tri
cac viet » bac viet, ca viet, tac viet
ve cham » va cham, ve chat, vu cham
va tinh » may tinh
nang xa » nang x, lang xa, nang ma
thu san » thuy san, thu ban, phu san
ve cai » va cai, ve cac, ve tai
san ky » sang ky, van ky, dan ky
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu san ky nang xa hoi. hieu ((ve cai) or (ve cham)) xuc va tinh tri ((cac viet) OR (cach viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang xa hoi. hieu ((ve cai) OR (ve cham)) xuc va tinh tri ((cac viet) OR (cach viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky nang xa hoi. hieu ((ve cai) or (ve cham)) xuc va tinh tri ((cac viet) OR (cach viet))".
• Adding a wildcard symbol may retrieve word variants: thu san ky nang xa hoi. hieu ((ve cai) or (ve cham)) xuc va tinh tri ((cac viet) OR (cach viet))*.
