Perhaps you should try some spelling variations:
thuoc dang » thuoc dung, thuoc khang, thuc dan
nam thuoc » nam thuc, nam thu, nha thuoc
cua triet » cua viet, su triet
dang hanh » dang thanh, ban hanh, dang van
thien van » thi van
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
hanh di » hanh vi, hanh de, hang di
tu san » thu san, tu ban, tu can
tu sac » tu sach, tu cac, tu bac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (tu san)) ky nang xa hoi. thien van nam thuoc dang hanh di ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky nang xa hoi. thien van nam thuoc dang hanh di ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu san)) ky nang xa hoi. thien van nam thuoc dang hanh di ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (tu san)) ky nang xa hoi. thien van nam thuoc dang hanh di ((cua triet) OR (va triet))*.
