  In this paper, we provide a correct proof for the lower bounds of the local
antimagic chromatic number of the corona product of friendship and fan graphs
with null graph respectively as in [On local antimagic vertex coloring of
corona products related to friendship and fan graph, {\it Indon. J. Combin.},
5(2) (2021) 110--121]. Consequently, we obtained a sharp lower bound that gives
the exact local antimagic chromatic number of the corona product of friendship
and null graph.
