Perhaps you should try some spelling variations:
danh sai » dung sai, danh bat, danh dau
danh vai » danh va, doanh van, dang van
ve cham » va cham, ve chat, vu cham
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
ve cam » ve cac, va cam, ve cai
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 nang xa hoi. hieu ((ve cam) OR (ve cham)) luc va ((danh vai) or (danh sai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) luc va ((danh vai) OR (danh sai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) luc va ((danh vai) or (danh sai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) luc va ((danh vai) or (danh sai)) cua tre*.
