Perhaps you should try some spelling variations:
thuat sach » thuat san
thuat lanh » thuat lap, thuat san
van hanh » van thanh, ban hanh, van anh
dau tren » dau tien, dat tren, dau tieng
lang xa » lang ha, dang xay, lang van
qua cau » quan cau, qua cac, qua ca
cau xuc » cam xuc, cau luc, cau truc
xuc van » duc van, luc van, vuc van
y lang » o lang, _ lang, tay lang
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) OR (thuat lanh)) y lang xa hoi. hieu qua cau xuc van hanh vi dau tren~".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) OR (thuat lanh)) y lang xa hoi. hieu qua cau xuc van hanh vi dau tren*.
