We recall the classical Yaglom's limit theorem for the branching processes, and take the finite Markov chain as an example to explain why the quasi-stationary distribution is interesting. After reviewing the QSD's for the regular birth-death processes and one-dimensional diffusion processes, we show the existence and domain of attraction of QSD's the above processes which are irregular.
