If you delete the historical records of Himalayan listening to books, it may be because of the following reasons that you can't find the names of novels you have heard before:

1. History has been cleared: If you have recently cleared the history of Himalayan listening books, your previous collections will also be deleted.

2. Abnormal account number or login problem: If multiple accounts are used to log in to the same device, there may be problems such as data loss when switching accounts. In addition, if you haven't logged in for a long time or your account is abnormal, it may also cause your history to disappear.

3. Application failure: Sometimes the application itself has defects or failures, which may also lead to the loss of historical records.

In view of the above situation, I suggest you try the following solutions:

1. Check whether the history has been cleared by misoperation, and confirm whether the current account has been cancelled and logged in again;

2. If multiple accounts are used, please ensure that only one valid account is used for operation at a time;

3. Try to uninstall and reinstall Himalayan reading software and check whether the previous history can be restored.

In short, it is necessary to determine the specific reasons and take corresponding measures to solve the problems of not finding the title of the novel.
