Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
nang xa » nang x, lang xa, nang ma
va danh » va dinh, va dan, va hanh
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
ve cac » va cac
vi cua » vai cua
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: vu sac ky nang xa hoi. hieu ((ve cac) OR (vien cac)) nuoc va danh ((vi cua) OR (di cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang xa hoi. hieu ((ve cac) or (vien cac)) nuoc va danh ((vi cua) or (di cua)) tre*.
