After going through the Home Page of Ubuntu Kylin, I rather find no considerable difference between Ubuntu Kylin and Ubuntu with Chinese language set as default.
There are of course some special Chinese apps (Chinese lunar calendar, for example); but can't these apps be installed on Ubuntu as well?
So if I get an Ubuntu, customize it to have all the same apps as Kylin, and set Chinese as default language, what will be the difference between both?
What was the need of kylin, when ubuntu is itself so customizable?
There is no bad in bringing an custom Ubuntu for Chinese people.But there seems to be no reason for making it official.If we look at other official distros like lubuntu or xubuntu, they have a significant difference than ubuntu.This is not the case with kylin.It would only take, say 15 minutes to convert Ubuntu into Ubuntu Kylin.
It's just to be used as a national distro. Really deep there is no main differences between them but just to meet the needs of the Chinese government.
The Kylin OS was formerly developed by academics at the National University of Defense Technology in China. It was based on FreeBSD and was intended for use by the Chinese military and other government organizations. In 2013, the Chinese Government reached an agreement with Canonical for them to release a Chinese version of the popular Ubuntu distro and it will be used as a national OS.
For more information and check this.
ubuntu kylin is basically made for chinese people so with every software chinese language is prefferd and some of the default software and framework has been changed.

I think you are right; you can install standard Ubuntu and 'make it be Kylin' afterwards. One difference you don't mention is that fcitx is the default input method framework on Kylin (instead of IBus).
Kylin was of course created for the convenience of Chinese Ubuntu users.
If you are really looking for anythng that you cannot tweak on a pure Ubuntu installation to get the same end result as a Ubuntu Kylin installation, then there is not much. This is actually the same for other flavours, which you can install the related packages and modify the system to achieve the same thing. Just to make it clear, all flavours use the same repositories and so packages of all flavours have to be available to the whole Ubuntu family.
In addition, the purpose of Ubuntu Kylin is to create an image that users don't need to do those package install and tweaks to get a usable desktop. There are also a lot more than selecting the correct set of packages, to name a few:
Anyone can do the above without obtaining the Ubuntu flavour status, just start a whole new distribution and here you go. But the Ubuntu project does not object someone to start a flavour to achieve these goals, and being a flavour means Ubuntu Kylin will always follow Ubuntu guidelines and rules, play nice with the community and stay closely with the Ubuntu ecosystem.
