Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
thuc day » thuc vat
ve chat » va chat, van chat
hanh di » hanh vi, hanh de, hang di
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
di cua » dai cua, doi cua, de cua
cua tu » cua tuc, cua su, cua cu

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) OR (thuc dan)) hanh di 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) OR (thuc dan)) hanh di cua tu~".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu ((ve cac) or (ve chat)) ((thuc day) OR (thuc dan)) hanh di cua tu*.
