The official publication of GCPD e.V. is “Journal of the Society of Chinese Physicists in Germany” or “WULI”. The journal has the registered ISSN 1431 – 391X from 1992 to 1998 and the new ISSN 1438 – 5473 from 1999 on, which laid the foundation for the standardization of the journal and the increase of publishing samples. Since then, the journal has become an effective channel for information exchange among GCPD members and an important window of the society towards outside.
