“I started to make electronic music in the end of 2016, and at the same time I also started to write a book with my colleagues in China Youthology. This book is about today's social and cultural changes, and the status of young people and business. The book was written in 2017 and published in August 2018. The process of writing the book is also the process of making music. In the book, we call today's world "Great Plains" to describe a volatile society that is full of risks and opportunities. We call the state of people and organizations "nomadic". Therefore, I plan to make a trilogy of electronic music at the same time, to response to it.

In December 2017, the first album of the trilogy「The Abraham's Machine」was completed. This album was published in the Play Rec label in February 2018. In this album, the prophet Abraham disappeared, left behind him a machine. People bowed to the machine and prayed, thus the journey and a dialogue started and recorded. I used the Reason 10 software to create the album. I also included my poem entitled "Journey" written in Oxford Street Church in London in 2004.

「The Wild Ark」is the second album of the trilogy. It's about the Ark being not there, and the Great Plains a wasteland, and everywhere a boat. In the gloom, the sentient beings are scattered, surging, and boundless. Sky, dust, deep sea. Flying, creeping, sluggishing. Twelve tacks, twelve portraits. I used Ableton Live 10 software to create.

The third album of the trilogy has not yet been named and is already in progress. It's about the reflection of the people, and the reorganization of the social contract. “

“大概 2016 末年开始做电子音乐的同时，我也在跟我在青年志的同事一起着手准备写作一本书。有关今天的社会和文化变化，以及年轻人和商业的状况。书在 2017 年写完，在 2018 年 8 月出版。写书思考的过程，基本上也是我做音乐的过程。在书里，我们称今天充满风险与机遇，高速流变的世界为大平原，而人和组织的状态为游牧。因此，我也同步计划做电子音乐的三部曲，算是另外一种回应。

2017 年 12 月，第一部【亚伯拉罕的机器 The Abraham‘s Machine】完成，并于 2018 年 2 月在 Play Rec 厂牌发表。关于先知亚伯拉罕消失，只有他留下的机器。人们向机器跪拜诉说，展开一次旅程，一场对话。我用了 Reason 10 软件来创作。我也在唱片里，附上了自己在 2004 年在伦敦牛津街教堂写的一首名为【旅程】的诗。

【荒舟 The Wild Ark】是第二部。关于方舟不在，而大平原为荒，处处为舟。幽暗之处，众生各自散落，涌动不绝，无边无际。天空，尘泥，深海。游翔，蠕动，呆滞。十二首，十二个肖像。我用了 Ableton Live 10 软件来创作。

第三部尚未命名，已经在着手中。关于人的自省，以及契约的重订。”
