Perhaps you should try some spelling variations:
dang dinh » dang sinh, dang dieu, dang hanh
cau tren » cu tren, dau tren, cau treo
dau tien » van tien
te sach » toc sach
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
va dang » van dang, va nang, va lang
ca tren » cu tren, la tren, co tren
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang x hoi. hieu va cam xuc va dang dinh ((((cau tren) OR (ca tren))) or (dau tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu va cam xuc va dang dinh ((((cau tren) OR (ca tren))) OR (dau tien))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu va cam xuc va dang dinh ((((cau tren) OR (ca tren))) or (dau tien))*".
