If the title number of the master's thesis is wrong, it needs to be revised to make the format of the thesis conform to academic norms. The specific modification method is as follows:

Find the wrong position of the serial number, check it carefully and determine the correct serial number.

If it's just a simple book title with a wrong serial number, just delete the wrong serial number and rewrite the correct serial number.

If the title does not correspond to the content, it is necessary to readjust the title and content of the whole article to make it consistent.

When modifying the serial number, we need to pay attention to the overall format and typesetting of the paper to avoid other problems caused by modifying the serial number.
