Kokuto:
Asked a long time Tan Jian Ci fan, and it turns out that the Barley name for fans is from the M.I.C. days. It was a fan name for the entire group and after the group disbanded, Tan Jian Ci's fans continued to use the name, until they and Tan Jian Ci came up with XTH for his own fans.
Thanks for the interesting info! It got me looking for date of disbanding, but I did not find it. In fact, it's true that last activity seemed to go back to 2018, after the release of an album in 2017 and the retrospective MV from 2017 that I mentioned.
But I am not the only one not to know when they disbanded, as there is no mention about it on the pages about them. Also, this post on Twitter (X) : https://twitter.com/priestnovellove/status/1736645006457540762 showing Tan Jianci with his friend Jackson Wang, the "Hong Kong rapper, singer, songwriter, dancer and fashion designer, member of the South Korean boy band Got7, and founder of record label Team Wang", seemed to imply JW was unaware of their disbandment too in December 2023? So, it was an unofficial disbandment or just "going into extended sleep", fading away while former M.I.C. members went focusing on other solo career ?
