Perhaps you should try some spelling variations:
thanh thai » thanh hai, thanh tai, nhanh thai
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cua tre » cua te, cuu tre, dua tren
ve cham » va cham, ve chat, vu cham
su sai » su tai, su hai, su dai
sai ky » sac ky
ve cam » ve cac, va cam, 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 sai ky dang xa hoi. hieu ((ve cam) OR (ve cham)) duc va thanh thai ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky dang xa hoi. hieu ((ve cam) OR (ve cham)) duc va thanh thai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky dang xa hoi. hieu ((ve cam) OR (ve cham)) duc va thanh thai ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su sai ky dang xa hoi. hieu ((ve cam) OR (ve cham)) duc va thanh thai ((cua tre) or (cua triet))*.
