We consider mean field equations: $\Delta u+\rho(\frac{he^u}{\int_Mhe^u}-1)=0\, on M,$ where $M$ is a compact Riemann surface with area 1, $h$ is a positive continuous function and $\rho$ is a constant, or

$\Delta u+\rho\frac{he^u}{\int_\Omega he^u}=0$ in $\Omega,$
$u=0 on \partial\Omega,$

where $\Omega$ is a bounded $\mathcal{C}^1$ domain of $\mathbb{R}^2$. In this paper, we give a short survey on the uniqueness problem, find sharper estimates of bubbling solutions and count the topological degree of solutions.
