This site is great for ear training!

Have you considered adding a section for difficult to distinguish initials?
Like ju/zhu, nü/nu, xia/sha, xiang/shang, qun/chun, quan/chuan, jiong/zhong

..and Finals?
yan/yang, men/meng, yin/ying, lian/liang, yun/yuang, xuan/xun, kuan/kuang

Thank you

Thanks for the feedback! I think that is a very good suggestion. I did originally plan to try and tackle other problem sounds as well but somehow that got lost along the way in the development process. I could certainly think about including something like that in a future upgrade to the website.
