Perhaps you should try some spelling variations:
hieu thien » hieu hien, chieu chien, dieu khien
thien hach » thien thanh, hien hanh
nang xa » nang x, lang xa, nang ma
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
du van » duy van, duc van, vu van
tu van » tu va
vi cua » vai cua, di cua
cua te » cua tu

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu thien hach ((du van) OR (tu van)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu thien hach ((du van) OR (tu van)) hanh vi cua te*.
