Perhaps you should try some spelling variations:
hanh thai » nhanh thai, hinh thai, hanh tai
cua triet » cua viet, su triet, va triet
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va thanh, va danh
su hai » su tai
va cam » va cham, va cac, va cao
hai ky » thai ky, hoi ky, hai ly
ve cam » ve cham, ve cac, ve cai

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su hai ky dang xa hoi. hieu ((ve cam) OR (va cam)) duc va hanh thai ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su hai ky dang xa hoi. hieu ((ve cam) OR (va cam)) duc va hanh thai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su hai ky dang xa hoi. hieu ((ve cam) OR (va cam)) duc va hanh thai ((cua tre) or (cua triet))*".
