Status and prospects of the $\chi_{c1}(3872)$ at BESIII

The $\chi_{c1}(3872)$ serves as a pivotal role for understanding hadronic structures, remaining one of the most extensively studied exotic particles despite the experimental discovery of numerous unconventional hadronic states. Sustained experimental and theoretical investigations into the particle over the past two decades have propelled its study into a high-precision regime, marked by refined measurements of its decay dynamics and line shape, thereby offering critical insights to resolve longstanding debates between molecular, tetraquark, hybrid, and charmonium interpretations of this particle. The BESIII experiment has made seminal contributions to the study of the $\chi_{c1}(3872)$, leveraging its unique capabilities in high-statistics data acquisition and low-background condition. This article gives a concise review and prospects of the study of the $\chi_{c1}(3872)$ from the BESIII experiment.
