Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
ban hang » ngan hang
vu sach » vu bach, su sach, vu khach
hai cua » thai cua, dai cua, hoi cua
vai cua » dai cua, lai cua, bai cua
sach ky » sac ky, sach y, sach ty
cam cuc » cam xuc, cham cuu, pham cuc
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma

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: vu sach ky nang xa hoi. hieu va ((cam cuc) OR (pham chuc)) ban hang ((vai cua) OR (hai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang xa hoi. hieu va ((cam cuc) or (pham chuc)) ban hang ((vai cua) OR (hai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang xa hoi. hieu va ((cam cuc) or (pham chuc)) ban hang ((vai cua) OR (hai cua)) tre*.
