Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hoc sach » hoc sinh, hoc anh
hanh vai » hanh vi, hanh va, hanh tai
hoc cac » hoc cao
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
cac lo » cac lop, cac bo, cac ho
cac co » cac cong

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: ((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu va ((cac lo) OR (cac co)) va hanh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu va ((cac lo) or (cac co)) va hanh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) OR (hoc cac)) ky nang xa hoi. hieu va ((cac lo) or (cac co)) va hanh vai cua triet*.
