The first floor of the front section served as the facade of 'Chang Yuan Hospital,' where the second-generation owner, Dr. Xu Du, practiced medicine and examined patients. It carries the memories of local residents waiting for treatment. The original medicine cabinets and patient record forms remain, outlining the daily contours of modern medicine's early days in Lukang. The murals and inscriptions on the walls were commissioned by the first-generation owner, Xu Liang, when he purchased this townhouse in 1923. He invited Lukang calligrapher Wang Xipin and Guo school painting masters to create these works, which were important preservation items during the restoration project. Today, this area is designed as a permanent exhibition space, inviting visitors to view the past and present of Chang Yuan Hospital through historical artifacts and displays on the development of medical practices.

The courtyard connecting the main Western-style building and the first and second sections of the Chinese-style townhouse features a drainage well and brick paving. This was once the space where the Xu family entertained guests, enjoyed the cool air, or parked their vehicles. In the 1960s, the corridor pillars were removed to expand the space. From here toward the 'inner hall' that houses the Xu family shrine, one can see the elaborate Western-style decorative elements on the facade of the second section, including intricate floral stucco reliefs, keystone arches, and acanthus leaf extensions from the column capitals, showing the transitional trajectory of architectural aesthetics over time. This area now serves as a service hub with a counter for ticket sales and visitor inquiries. It also offers aiyu jelly in the shape of a Nikon S2 camera, as well as 'Carved Flower Cake' created in collaboration with the century-old 'Zheng Xing Zhen Bakery,' molded after the stucco reliefs on the facade.

The first floor of the central hall was the Xu family shrine where they held ancestral ceremonies and religious worship, as well as a dining space for family gatherings. This attachment to home is embodied in the daily routine of Grandmother Xu, Ms. Shi Xiuxiang: even during the period when the old house awaited transformation, she continued to come here to clean the space and worship for decades without fail. For this reason, the restoration team built temporary passages and structures to ensure the uninterrupted burning of incense that retained the most authentic warmth of the central hall. Ascending the stairs, the area above the atrium was once a corner where children read and wrote. The daylight that once fell upon book pages now warms Wang Xipin's calligraphy on the walls and brightens the junction between old and new exposed bricks, reflecting the spectrum of cross-generational memories, family emotions, and the soul of the old house.

The 'front building' on the second floor was originally an atrium that was enclosed in the 1960s and used as Dr. Xu Du's living quarters and a venue for family concerts. In the past, family members would open the doors and windows to enjoy festival activities on Lukang Main Street from the arcade roof. Next to it is the 'Dreamland,' which was the living quarters of Dr. Xu's wife, Huang Shiyi, and still contains many antique furniture pieces. These private spaces have now been redesigned as exhibition areas, reinterpreting the music and moments of daily life in the past through special exhibitions and displays of family history. The restoration team preserved the aluminum windows that were replaced after the war, documenting the organic modifications made to accommodate usage needs throughout the house's nearly hundred-year history.

Originally designed with a full-bed layout, the beds were later removed due to termite damage, revealing beautiful hexagonal brick flooring. This space has now been transformed into the 'Old House Hospital,' repurposing the former Chang Yuan Hospital's medical setting into a platform offering consultation services for regeneration of old houses, complete with architectural-themed exhibitions. Visitors can learn about Chang Yuan Hospital's architectural design through detailed acrylic models and clay sculpture exhibits. On the other hand, if your old house is experiencing the test of time, you can also come here for a 'prescription' and receive regeneration advice.

This was once the room of the Xu couple when they were newlyweds, the bedroom of photographer Xu Cangze and his wife, and also the childhood residence of current owner Dr. Xu Zhengyuan. The Leica camera genealogy poster on the wall, treasured by Xu Cangze, concretely presents the profound bond between three generations of the Xu family and photography, foreshadowing this space's future transformation into a 'Light Sculpture Exhibition Room.' Today, the exhibition room features interactive light projection installations custom-designed by local team 'Guangmanlou.' Visitors can witness stories between Xu Cangze and his cameras by placing camera models in the sensing area, and experience darkroom development processes firsthand, engaging in dialogue with family memories in this seemingly ordinary living room.

Ascending to the third floor of the main building, the former 'living room' welcomes travelers with a central tea and snack bar. The spaces on either side present a fascinating contrast: one side preserves the traditional Japanese-style tatami reception area with soft lighting added behind sliding doors, creating an elegant and tranquil private tea space; the other side is designed as a brightly lit Western-style seating area, echoing the modernized everyday life during the Japanese Rule Period. The book selection here, compiled in collaboration with 'Boven Magazine Library,' allows visitors to browse publications and draw inspiration while enjoying both Japanese and Western aesthetics. Walking from the living room to the balcony, the intricate roof structure of the Chinese-style shophouse is within arm's reach. Take time to examine the 'hanging tile' technique used by the restoration team to match the shared wall, along with the clay sculptures on the roof ridge and the openwork brick details, visualizing how the undulating red tiles across the ancient town once accommodated the daily roof-traversing activities of Lukang residents.
