Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
ve cac » va cac, vien cac
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, duc va
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky nang xa hoi. hieu ve cac ((xuc va) or (((tuc va) OR (tuc xa)))) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. hieu ve cac ((xuc va) OR (((tuc va) OR (tuc xa)))) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. hieu ve cac ((xuc va) or (((tuc va) OR (tuc xa)))) hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu ve cac ((xuc va) or (((tuc va) OR (tuc xa)))) hanh vi cua triet*.
