You can sign up to that group to find out information about any upcoming meetup happening across the country. This should provide a more useful experience where you'll get more information about these events. The current system is based on cities, so if you were signed up to the Hyperledger Beijing group, for instance, you wouldn't learn about events in other areas.
We will provide two weeks for you to continue to be able to use the existing city-based Hyperledger groups on meetup.com and after that we will remove them and use the Hyperledger Mainland China group for any future communications.
Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply chains, manufacturing and Technology.
Hyperledger Meetup groups have an informal relationship with Hyperledger, and make up a key part of the Hyperledger ecosystem. Participation in a Hyperledger Meetup group is open to anyone--employees of a Hyperledger member company, Hyperledger contributors and developers, and people just passionate about blockchain technology.
