Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
cau triet » cau trieu, su triet, cua triet
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, va tinh
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cam duc » cam xuc, pham duc, nam duoc
cao duc » dao duc, cao suc, giao duc
cuu tre » cua tre, cau tren, cau treo

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky dang xa hoi. hieu van ((cam duc) OR (cao duc)) va thanh vai ((cuu tre) OR (cau triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky dang xa hoi. hieu van ((cam duc) OR (cao duc)) va thanh vai ((cuu tre) or (cau triet))~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky dang xa hoi. hieu van ((cam duc) OR (cao duc)) va thanh vai ((cuu tre) or (cau triet))*.
