+Hello, 中国!

+
+* Introduction
+
+We are thrilled to announce that the content on
+[[https://golang.org][golang.org]] is now available in mainland China through
+the name [[https://golang.google.cn][https://golang.google.cn]].
+The growing Go developer community in China can now directly access official
+documentation, technical articles, and binaries.
+
+The Go community in China is bigger than ever.
+In 2015, Robert Griesemer [[gopherchina][visited Shanghai]] to attend
+GopherChina, the first Go conference in the country.
+In the years since, it has become one of the largest Go conferences in the world
+with over 1200 attendees at their 2017 event.
+Over the same period, one of the most popular
+[[https://gocn.io][community-built Go forums]] saw their traffic increase
+threefold and the number of participants in Go-specific groups on social
+platforms like WeChat and QQ has grown to over 11,000 people.
+
+Go adoption within China-based companies has also increased, with
+[[https://www.qiniu.com/][Qiniu]], [[http://www.huawei.com/][Huawei]],
+[[http://www.alibabagroup.com/][Alibaba]], and countless others using Go heavily
+in their production stacks.

+
+We’re excited to provide even more resources for Go developers in China to
+supplement the excellent material already available to them, but this is just
+the beginning. We’ll be focusing on making Go more accessible to non-English
+speakers in 2018, so keep watching this space.
