Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
hang tai » hang va, dung tai
hang vai » hang va, hang hai, hang vi
vu sach » vu bach, su sach, vu khach
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
cam cuc » cam xuc, cham cuu, pham cuc
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang

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