Perhaps you should try some spelling variations:
hieu cao » chieu cao, hieu cac, hieu ca
chat hoc » chat hoa, chat thom, cho hoc
cau tren » cu tren, dau tren, ca tren
cau theo » cau thi, cau tao
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 lang xa hoi. hieu cao chat hoc va danh vi ((cau tren) OR (cau theo))~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu cao chat hoc va danh vi ((cau tren) or (cau theo))*.
