It's simple. Click the crosshairs on the historical K-line chart, move the vertical line to the previous K-line, and then press enter to see the time-sharing situation of the day. The latest version of Master Boyi can only find the time-sharing chart of any day within 7 months before the recent trading day. For example, the time-sharing chart of March 1 can be found as early as September 30 this year.
