Ubuntu Kylin is the official Chinese version of the Ubuntu computer operating system.
It has been described as a “loose continuation of the Chinese Kylin OS”. In 2013, Canonical reached an agreement with the Ministry of Industry and Information Technology of the People's Republic of China to co-create and release a Ubuntu-based OS with features targeted at the Chinese market. Ubuntu Kylin is intended for desktop and laptop computers.
The first official release, Ubuntu Kylin 13.04, was released on 25 April 2013, on the same day as Ubuntu 13.04. Features include Chinese input methods, Chinese calendars, a weather indicator, and online music search from the Dash.
In the latest release 14.10, it features its own Ubuntu Kylin Software Center (UKSC) and a utility which helps common end-users for daily computing tasks called Youker Assistant.
The team also cooperates with Sogou to develop Sogou Input Method for Linux. Since it is close sourced, it is not included in the official Ubuntu Kylin image, but users can download it from UKSC or Sogou's website.

Kylin (Chinese: 麒麟; pinyin: Qílín; Wade–Giles: Ch'i-lin) is an operating system developed by academics at the National University of Defense Technology in the People's Republic of China since 2001. It is named after the mythical beast qilin. The first versions were based on FreeBSD and were intended for use by the Chinese military and other government organizations. With version 3.0 Kylin became Linux-based, and there is a version called NeoKylin which was announced in 2010.
In 2013, it was announced that a new Linux-based operating system with the same name would be released using Ubuntu. The first version, Ubuntu Kylin 13.04, was released on 25 April 2013.

and noticed it is written by Jon Harrop. I'm sorry to say, he's truly a loud-mouthing idiot. (if you don't know, Jon Harrop is infamous as a “troll” for posting idiot posts to various comp.lang newsgroups and peddling his F# books or whatever he's doing)
discovered a new keyboard mechanical key switch, the Cherry ML switch. The interesting thing is that it's not a full depth key, but somewhat like laptop key, but taller. Yet, mechinacl switch. See: Cherry G84 4100 Keyboard
