Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
thuc va » thuc vat, thuc dan, thuc day
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
ve cac » va cac
vi cua » vai cua, di cua
cua te » cua tu

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

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