Can you tell me whether I can return the Beijing subway card or not?

The Beijing Transportation Smart Card(https://www.travelchinaguide.com/cityguides/beijing/transportation/smart-card.htm) can be return at many sites distributed at metro stations, bus companies and branches of China Citic Bank . Fewer offices accept refund service. Fuxingmen Subway Station is the only metro subway where you can refund it. Where are you in Beijing? You may find the nearrest site to your stay place to return it.
