Yesterday, ZRC's trading volume was 180 million, and today's trading competition increased by 20,000

Yesterday, SQD's trading volume was more than 60 million, but today it increased by more than 40,000

The minimum entry for the SQD trading competition was more than 110,000 (I remember it was only a few thousand three days ago), and the number of people was 13,000, which means the total trading volume reached at least more than 1.4 billion. But I just used my math level of graduating from kindergarten to count, and the total trading volume from SQD listing to now is only more than 500 million, so... did I calculate it wrong, or did I not understand it correctly?
