What do "Matsui" and "Gong Ji" on the drum tower in Cixian mean? Please give me some advice!

Matsui faces north and the arch faces south.

There are multi-layer sawtooth brick eaves around the abutment, and vertical columns are built on the eaves, and the piles are distributed in turn, with 58 * * *. These features on the abutment have been well protected and restored. The Drum Tower is built on it.

The roof eaves of the building are covered with pure glazed tiles, which are tower-shaped and shine under the sunlight.

The whole drum tower is a building facing south, and the main entrance is in the middle of the first floor. The plaque on the door is inlaid with the word "Drum Tower" inscribed by the famous calligrapher Qi Gong, and a stone tablet is erected on the west side of it, engraved with the title of "the first floor in the air" inscribed by the famous calligrapher Ouyang Zhongshi.
