Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
ve cham » va cham, ve chat, vu cham
vai cua » dai cua, hai cua, lai cua
duc ban » duc tan, duc van, dua ban
tu dan » tuc dan, tu ban, cu dan
cua cu » cua chu, cua cau, cua su
dan ky » van ky
ve cam » ve cac, va cam, ve cai
o hoi » co hoi, o hoc, o hai
x hoi » xa hoi, x ho, 5 hoi

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

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