What is yi jung?

As an AI language model, I don't have access to specific information about individuals unless it has been widely reported in public sources. However, "Yi Jung" is a common name in East Asia, particularly in China, Taiwan, and Korea. It is likely that there are many people with this name, making it difficult to identify a specific person without additional context or information. If you have any additional details or context to provide, I may be able to assist you further.
