Abstract: With the help of the general vertexdistinguishing total colorings of a star, we discussed the general vertexdistinguishing total colorings of corona graph of 2K₂∨K₁. Under the  general vertexdistinguishing total colorings of the star, the colorings of pendent edges of the star were in an ascending order and finally it was expanded into the general vertexdistinguishing total colorings method of corona graph of 2K₂∨K₁. The general vertexdistinguishing total chromatic numbers of corona graph were got by depending on the number of pendent edges.

Key words: corona graph, general total coloring, general vertexdistinguishing total coloring, general vertexdistinguishing total chromatic number
