Hi songpaoi khamkeaw,
Unfortunately Youtube as rejected you application to become part of the Sezela network. The reason for this is as follows:
Both your channel and the network your channel have been part of, have had strikes. This can be related to copyrighted audio and/or video, or to certain types of footage. Read our guidelines for more info http://www.zoomin.tv/site/index.cfm/action/copyrightkit-guidelines/section/music and check Youtube's guidelines http://www.youtube.com/t/copyright_center and http://www.youtube.com/t/terms

This doesn't mean that you do not have a cool channel! It just means that you will need to sort out the issues listed above and simply re-apply once you're done.
Best,
Sezela
