Perhaps you should try some spelling variations:
thieu nien » thien nhien
nien cac » vien cac, dien cac, bien cac
tuc tuan » duc thuan, quoc tuan, tuc thanh
va triet » va trien, ve triet, cua triet
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cac tuc » cac toc, cac tu, cac tac
anh vai » anh va, anh bai, anh van
su sac » su sach, su xac
su cac » tu cac, su cao, su can

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 cac)) ky dang xa hoi. thieu nien cac tuc tuan anh vai ((va triet) OR (va thiet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky dang xa hoi. thieu nien cac tuc tuan anh vai ((va triet) OR (va thiet))~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky dang xa hoi. thieu nien cac tuc tuan anh vai ((va triet) OR (va thiet))*.
