Perhaps you should try some spelling variations:
pham chuc » pham huu, kham chua, pham huy
ban hanh » ban hang
hanh hai » thanh hai, nhanh hai, hang hai
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet

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

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