Heavy flavor physics is closely related and cross-integrated to all directions in high-energy physics. High-precision calculation and effective theory development is important to precisely test the standard model and hunt for new physics. In this talk, I will introduce the latest status for the study of beauty-charm meson family, and then report the two-loop calculation for the decay constant of vector beauty-charm meson. Concerning the nonconvergence of the recent three-loop correction to the decay constants, we try to give a reasonable solution which simultaneously explain the hyperfine splitting and convergent decay constant.
