Abstract: Based on the results by HAN Mao-an, et al. for computing
some focus values of non-smooth Li\'{e}nard systems, the number of
limit cycles bifurcated from the origin of some more general
non-smooth Li\'{e}nard systems were given by using maple process.

Key words: \Li\'{e}nard systems, focus values, Hopf cyclicity
