According to online reports, according to the ThreeDAO public account of Wanxing Island, Xiao Feng, founder of Wanxiang blockchain, suggested that the Ethereum Foundation set up an office in Hong Kong in a private exchange with Vitalik. Xiao Feng pointed out that blockchain developers are mainly concentrated in the English-speaking world and the Chinese world. Losing the China market means losing important global developer resources. Vitalik said that the development force of the Ethereum Foundation in Berlin is mainly engaged in the underlying technology work, but at present, the underlying technology of Ethereum has matured, leaving only room for optimization. Xiao Feng said that he once told Vitalik half-jokingly:"We have the 11th Blockchain Conference in Shanghai in October. If you come and get arrested, I will accompany you to prison." Later, he pointed out that this was just a joke, and said that in fact, China's technology departments, government agencies and developer groups respect Ethereum technology and suggested that the foundation should not stay away from the China market.
