Perhaps you should try some spelling variations:

hanh vu » hanh va, hanh tu, hanh ve
ve cham » va cham, ve chat, vu cham
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
ve cam » ve cac, va cam, ve cai
sac ky » cac ky, sai ky
tuc va » thuc va, truc va, tuc xa
tu sac » tu sach, tu cac, tu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky dang xa hoi. hieu ((ve cam) or (ve cham)) tuc va ((hanh vu) OR (hanh vi)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dang xa hoi. hieu ((ve cam) OR (ve cham)) tuc va ((hanh vu) OR (hanh vi)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang xa hoi. hieu ((ve cam) or (ve cham)) tuc va ((hanh vu) OR (hanh vi)) va triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky dang xa hoi. hieu ((ve cam) or (ve cham)) tuc va ((hanh vu) OR (hanh vi)) va triet*.
