Introduction to the three stele corridors: To the west of the inkstone-washing pond, there is a corridor surrounding it, which is more than 100 meters long. There are more than 50 marble steles embedded in the corridor walls, which were inscribed by famous calligraphers across the country when they rebuilt the former residence. The inkstone stele pavilion is located in the north sky view. A high marble platform is built, and a stone stele of "book drying platform" is erected on the platform. There are also halls and famous academies built in the northern part of Taipei, which display the inscriptions and stone carvings of calligraphers and the fine works of famous calligraphers from all over the country.
