Power corrections are crucial for the frontier precision study at colliders, and soft quarks play an important role starting from next-to-leading power. However, renormalizing soft-quark functions and, hence, deriving their anomalous dimensions are hard and have only received progress recently. In this talk, I will show how to renormalize several soft-quark functions entering the Higgs form factor and the Drell-Yan process in the position space concisely. In particular, I will also illustrate how to extract UV poles consistently in the context of introducing offshellness-related IR regulators inherited from factorization formulae.
