According to the British "Financial Times" website reported on June 4, recently, Bank of Beijing posted online recruitment advertisements to recruit programmers who use the computer programming language Python and other developers who are familiar with open source big data such as Hadoop. According to the report, although there are many Chinese technical talents, programmers and blockchain developers are almost all attracted to China's well-known technology giants. Such companies also dominate China's financial technology industry. Alibaba's Ant Financial and Tencent's WeChat payment form a double monopoly on digital and mobile payments. They are the gateway to the world's largest e-commerce and financial technology services ecosystem.
