Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
day hanh » day nhanh, day thanh, dao hanh
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
ve chat » va chat, van chat
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
di cua » doi cua, de cua, do 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: su sach y nang xa hoi. hieu ((ve cac) OR (ve chat)) thuc day hanh ((di cua) OR (dai cua)) tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ((ve cac) or (ve chat)) thuc day hanh ((di cua) OR (dai cua)) tu~".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu ((ve cac) or (ve chat)) thuc day hanh ((di cua) OR (dai cua)) tu*.
