If a publishing house buys the copyright of a book with 10 million yuan (assuming), then the author's income is 10 million yuan, and then the money bought by the publishing house has nothing to do with the author.

One is dividends, assuming that the author's rate of return is 10%, and the author's income is 20 *100000 * 10% equal to 200000.

The rate of return depends on the price of the book or its net profit.
