 ) in black hole X-ray binaries have remained a long-standing puzzle. A lea
 ding explanation attributes these oscillations to general relativistic Len
 se–Thirring precession of the tilted\, hot inner accretion flow\, but di
 rect observational evidence has been elusive. In this talk\, I will introd
 uce a novel X-ray data-analysis method designed to identify the characteri
 stic signatures of accretion flow precession. Applying this method to X-ra
 y observations\, we detect significant signatures predicted by the precess
 ion model\, providing strong observational support for this scenario. I wi
 ll also discuss prospects for further testing this model with the future e
 nhanced X-ray Timing and Polarimetry mission (eXTP).\nBiography:Qingcang S
 hui (税擎苍) is a new TDLI postdoc. He received his Ph.D. from the Inst
 itute of High Energy Physics\, Chinese Academy of Sciences\, in 2026. His 
 research focuses on black hole accretion physics\, particularly X-ray vari
 ability\, using advanced data-analysis techniques and numerical simulation
