Perhaps you should try some spelling variations:
pham chuc » pham duc, kham chua, pham huy
hanh vai » hanh vi, hanh va, hanh tai
thu nang » thi nang, thu hang, thu bang
hieu van » hieu va, thien van, lieu va
pham huu » pham duc, pham duy, phan huy
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
so sach » so sanh, co sach, hoc sach
nang xa » nang x, lang xa, nang ma
bo sach » co sach, hoc sach
cua te » cua tu

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: ((so sach) OR (bo sach)) thu nang xa hoi. hieu van ((pham chuc) OR (pham huu)) va hanh vai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (bo sach)) thu nang xa hoi. hieu van ((pham chuc) or (pham huu)) va hanh vai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (bo sach)) thu nang xa hoi. hieu van ((pham chuc) or (pham huu)) va hanh vai cua te*.
