A self-designed postcard showing spots of lights in the dark. Thanks Anastasia.
A 4.20 Yuan bird definitive stamp was used. It was neatly cancelled with postmark of Nanning Pingxin (Tongqu) 2 or 南宁 平信（筒取）2 in Chinese on 5.7.2010. A postage due cancellation is stamped with 30/400 written to indicate short of 30 Fen for airmail postcard rate.
