The music is from TSAR:https://www.bilibili.com/video/BV1kU4y1x7mN
I got wrong BPM that led to a problem that I always hold "F" to chart.THIS IS BAD

Update:some mistiming parts got fixed,and bpm fatal bug fixed OMG
ANYWAY GAV AND PROG ARE GOD
Thanks to Prog for the correct bpm and time signature
Thanks to gav for finding Problems
Thanks to Halflite for checking
Alert: this chart is unfriendly to controller,because of Stride Strigs
