1. Loss of literary value: Many online literature works lack the literary value of traditional literature works, such as depth, ideology, artistry, etc. They often only pursue the success of traffic and commerce and lack real literary value.
2. Uneven quality of content: The main creators of online literature are usually young web novelists. Their writing level, literary attainment, and creative style are uneven. In addition, the audience of online literature was also unstable, and the quality of the works was difficult to be widely recognized.

Some networks and the theft of other people's works to obtain benefits not only damage the intellectual property rights of the original author but also affect the overall image of online literature.

The existence of these problems makes the development of online literature face challenges and opportunities. It requires the network, literature institutions, readers and supervision departments to work together to promote the healthy development of online literature.
How long has the history of the development of Chinese characters been?The development of Chinese characters had a long history that could be traced back to ancient times thousands of years ago. The origin of Chinese characters can be traced back to the hieroglyph. This kind of writing originated by drawing an object to represent a word.

The ideograms referred to the characters that represented words and meanings with strokes, such as Chinese characters. Chinese characters are one of the largest characters in China. There are a total of 3600 different Chinese characters, each of which has its own meaning and usage.
The phonological characters referred to characters that used phonology to represent words and meanings, such as Pinyin. Pinyin is an important part of Chinese characters and the foundation of Chinese language teaching. Pinyin formed new words by combining different initial and final sounds. This way, there was a close connection between pronunciation and words.
