Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
van thanh » ban thanh, van tuan
thanh vi » hanh vi, thanh va, thanh ve
dau tren » dau tien, dat tren, dau tieng
lang xa » dang xay, lang van
lang ha » long ha
qua cau » quan cau, qua cac, qua ca
cau xuc » cam xuc, cau luc, cau truc
xuc van » duc van, luc van, vuc van
vi dau » vi dai, va dau, bi dau

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: "thuat sach _ ((lang xa) OR (lang ha)) hoi. hieu qua cau xuc van thanh vi dau tren~".
• Adding a wildcard symbol may retrieve word variants: thuat sach _ ((lang xa) OR (lang ha)) hoi. hieu qua cau xuc van thanh vi dau tren*.
