Perhaps you should try some spelling variations:
thuc dan » thuc hanh, thuc vat
te sach » toc sach
sach ly » sach y, sach lo, sach ty
ly nang » ky nang, ly hang, ly vang
hieu ve » hieu va, hieu van
ve pham » vi pham, v pham, ve phan
dan lap » phan lap, dan luan
lap cua » lai cua, tap cua, lam cua
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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: "te sach ly nang x hoi. hieu ve pham ((thuc dan) OR (hoc dan)) dan lap cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang x hoi. hieu ve pham ((thuc dan) OR (hoc dan)) dan lap cua te*.
