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
dau va » dau ve, lau va
vi cua » vai cua, di cua
cua te » cua tu
du va » su va, vu va, do va

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: tu sac ky nang xa hoi. hieu thien hach ((((du va) OR (tu va))) OR (dau va)) hanh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu thien hach ((((du va) or (tu va))) or (dau va)) hanh vi cua te*.
