Jinrong smiled and looked back at Duke An, answering with a laugh, "I have already discussed this matter with His Majesty. Wan Yan from my mansion is very knowledgeable about rail transportation of materials. When the court decided on rail transportation, Uncle Wan was in the capital. Upon learning that the court planned to initiate railway carriages, Uncle Wan instructed the advisors staying back at the prince's mansion to take on part of the railway project if an opportunity arose. The advisors in the prince's mansion are indeed capable, and they handled this matter quite well. If the railway carriage operation is successful, it will be a highly profitable affair."
