As can be seen from the screenshot of the official website of the game management committee, the alpha test started on April 9 and ended on April 13. The number of participants was 19999, and the rating was above teenagers. It is not clear whether the test is only aimed at Hanfu or universal? Moreover, the number of participants in 19999 is not the actual number, which seems to be the upper limit of the number of participants in the game test stipulated by South Korean Law (20000).
In addition, the announcement has been removed from the official website of the game management committee, and Blizzard has not officially announced the schedule of game testing.
