There could be many explanations for the answer to this question. Here are some possible explanations: Traditional Chinese characters were once the official language in history, so they were widely passed down and used in the long history. Therefore, many people may be born with the ability to easily recognize and read traditional characters because they have already formed the corresponding traditional characters in their minds. Reading traditional characters requires less brain capacity because its structure is more compact than simplified characters. This may explain why some people can understand the traditional text very fluently when they read it but find it difficult when they try to write it. Writing requires deeper understanding and memory. Writing involves many different aspects such as grammar, vocabulary, spellings, punctuations, and so on. For many people, it takes more time and energy to maintain the same in these different aspects. Writing also required creativity and imagination. Although some people may be born with the ability to recognize and read traditional characters, they may lack the creativity and imagination needed to write. As a result, they may feel a lack of inspiration and creativity when writing. It should be noted that the above are only some possible explanations. The specific situation may vary from person to person.
