Although NetEase completed the entire execution process by itself, Li Yin repeatedly emphasized another participant in the event-Hangzhou-Hong Kong Metro. This joint venture between Hangzhou Metro Group Co., Ltd. and MTR Corporation Limited has always played a role in assisting the promotion, which has also become one of the reasons for the rapid implementation of the event.

In Beijing, the Beijing-Hong Kong Metro, in which MTR Corporation Limited has a stake, is also a partner that the advertising and marketing circle is willing to cooperate with. They have teamed up with partners such as One Direction Space to launch many high-quality advertisements. For example, the "Master's Words" series of advertisements on Line 14 were widely circulated on social media. There are already more and more users from Beijing, Shanghai, Guangzhou and other cities, hoping that NetEase Cloud Music can optimize the subway space in their cities. Li Yin and her team are seriously considering such suggestions, after all, they have a large amount of good quality content in their hands. Migrating content carriers is not difficult. The important thing is to find open-minded and tolerant partners like Hangzhou-Hong Kong and Beijing-Hong Kong. Behind this, the optimization of travel space is becoming a problem that urban operators must face. Another psychological need that is difficult to meet among white-collar workers in big cities is another. NetEase Cloud Music found a way to connect the two, and then it won.
