我只不过是一个讲故事的人
[wŏ zhĭ bù guò shì yī gè jiăng gù shì de rén]
This means 'I'm just a storyteller'. This kind of net name implies modesty, suggesting the person is humble and merely shares stories, or it may also imply the person has experienced a lot in life, viewing themselves as someone who narrates different chapters.
