Perhaps you should try some spelling variations:
thien nang » thien bang, thien dang, thien cong
trien nang » trien nong, trien mang, trien quang
thu sach » tu sach, thuat sach, thuoc sach
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, xuc ban
hieu ve » hieu va, hieu van
cuu tre » cua tre, cau tren, cau treo
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((thien nang) OR (trien nang)) xa hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((thien nang) OR (trien nang)) xa hoi. hieu ve cam xuc van hanh vi ((cua te) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((thien nang) OR (trien nang)) xa hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thu sach ((thien nang) OR (trien nang)) xa hoi. hieu ve cam xuc van hanh vi ((cua te) or (cuu tre))*.
