Yanyi came into contact with computer music production and recording and mixing knowledge. With almost no information sources at the time, he learned arrangement and post-production techniques by translating foreign language materials and exploring pirated software on his own. Later, I founded Oasis Music Network, which became the top 3 professional audio technology website in China at that time. I also wrote a large number of arrangement and mixing technical articles under the pseudonym "Night Knight", which were published in many technical forums such as MIDIFAN.
