Abstract
We prove that a general complex Monge–Ampère flow on a Hermitian manifold can be run from an arbitrary initial condition with zero Lelong number at all points. Using this property, we confirm a conjecture of Tosatti–Weinkove: the Chern–Ricci flow performs a canonical surgical contraction. Finally, we study a generalization of the Chern–Ricci flow on compact Hermitian manifolds, namely the twisted Chern–Ricci flow.

Notes
After this paper was completed, the author learned that Xiaolan Nie proved the first statement of the conjecture for complex surfaces (cf. [26]). She also proved that the Chern–Ricci flow can be run from a bounded data. The author would like to thank Xiaolan Nie for sending her preprint.
