Perhaps you should try some spelling variations:
thuoc vat » thuc vat, thuoc va, thuoc bat
nam thuoc » nam thuc, nam thu, nha thuoc
hanh nam » thanh nam, hanh lam, hanh ngay
thi hanh » thi thanh
vat hanh » vat thanh, van hanh, va hanh
ve triet » va trien, su triet

hanh di » hanh vi, hanh de, hang di

v nang » va nang, vu nang, van nang
di ve » dai ve, de ve, do ve

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 sach ((y nang) OR (v nang)) xa hoi. thi hanh nam thuoc vat hanh di ve triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) xa hoi. thi hanh nam thuoc vat hanh di ve triet*.
