Perhaps you should try some spelling variations:
pham cua » pham ca, phat cua, ham cua
ban hanh » ban hang
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
ky dang » ky nang
ky danh » ky anh
hieu ve » hieu va, hieu van
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ky dang) OR (ky danh)) xa hoi. hieu ve ((cam xuc) or (pham cua)) ban hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky danh)) xa hoi. hieu ve ((cam xuc) OR (pham cua)) ban hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) OR (ky danh)) xa hoi. hieu ve ((cam xuc) or (pham cua)) ban hanh vai cuu tre*".
