My membership level in J-Club program is currently Black. I can't figure out what this elite level is about, cause there is no description for it in their terms. I wasn't able to find anything. Maybe it is written in Chinese, but unfortunately I can't understand it.
All the information on their website is only about three elite levels: Silver, Gold and Platinum.

Could you please tell me where Black elite level from? Is it higher or lower than Silver level, for example?

I would appriciate any information, thank you.
