Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thai cua » than cua, tai cuc, tri cua
anh thai » anh thi, anh tai, nhanh thai
vien da » vien dai, hien dai
van anh » van thanh, tuan anh, van minh
nang xa » nang x, lang xa, nang ma
duc van » duc va, duc tan, duc manh
su sac » su sach, su cac
ve cac » va cac, vien cac
su xac » pu xac, su cac

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 sac) OR (su xac)) ky nang xa hoi. hieu ((ve cac) OR (vien da)) duc van anh thai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky nang xa hoi. hieu ((ve cac) or (vien da)) duc van anh thai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky nang xa hoi. hieu ((ve cac) or (vien da)) duc van anh thai cua triet*.
