$M_{\rm 1i} =$ initial mass; $M_{\rm f} =$ the mass of hot subdwarfs; $q_{\rm i}=$ the mass ratio; $P_{\rm i} =$ initial orbital period; $P_{\rm f} =$ orbital period of hot subdwarf binaries; $M_{\rm env} =$ the envelope mass of hot subdwarfs; $t_{\rm age} =$ the lifetime of a hot subdwarf. More parameters can be seen from Figs. 2, 3, and 6-9.
