Specifically, the income from intellectual property refers to the property income that is actually obtained or has been clearly available during the marriage relationship. For its definition, it can be divided into the following situations: works created and published before marriage, if the contribution fee is obtained after marriage, it belongs to the actual acquisition during the duration of the marriage relationship, and it is the joint property of husband and wife; Although no contribution fee has been received for the works created and published after marriage, the contribution fee belongs to the property income that can be obtained during the duration of the marriage relationship. Even if it is realized after divorce, it is also the common property of the husband and wife; Works that have not been published at the time of divorce and have received royalties after divorce do not belong to the property that can be explicitly obtained during the existence of the marriage relationship, but belong to personal property.

 （1） Salary and bonus;
