Yuan Kuocheng's book Romance of the Three Kingdoms had 150 chapters, but there were only two parts, 1-150 and 251-365, on the disc. This could be because Yuan Kuocheng's book was not included in the 365 chapters of Romance of the Three Kingdoms, or because Yuan Kuocheng's book was shorter than the main body of Romance of the Three Kingdoms. If you're interested in Yuan Kuocheng's storytelling, you can search for his recordings online or buy his other works from physical bookstores so that you can better appreciate his voice and content.
