Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
va thanh » gia thanh, ban thanh, va tinh
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
cua chu » sua chua
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
ve cam » ve cham, ve cac, va cam
cua cu » cua cau, cua su, cua co
x hoi » xa hoi, x ho, 5 hoi
o hoi » co hoi, o hoc, o hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky nang ((x hoi) or (o hoi)). hieu ve cam duc va thanh vai ((cua cu) OR (cua chu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang ((x hoi) OR (o hoi)). hieu ve cam duc va thanh vai ((cua cu) OR (cua chu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang ((x hoi) or (o hoi)). hieu ve cam duc va thanh vai ((cua cu) OR (cua chu))".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang ((x hoi) or (o hoi)). hieu ve cam duc va thanh vai ((cua cu) OR (cua chu))*.
