An example of a nice and beautiful pen name with the word "Mo" was as follows: 1 Mu Mo (mü mü): From the Book of Songs,"Mu Er is like his wish" means to pursue his dreams. 2 Moruo (mü rü): It means bubbly beauty to describe the fresh and natural beauty of the protagonist. 3 Moyin (mü Yin): From the "Songs of Chu","sound moves inside and shape sounds outside" described the protagonist's inner voice and external performance. 4 Moxia (mü xià): It means the summer of bubbles to describe the beauty and freshness of summer. 5 Moan (mü àn): It means the shore on the water to describe the fresh and elegant character of the protagonist. I hope these pen names will be helpful. Of course, I can also design my own pen name according to my own preferences and creativity.
