二水公會堂

Ershui Public Hall

Ershui Public Hall (二水公會堂) is located in Ershui, a small town at the very southern edge of Changhua, on the border with both Yunlin (to the south) and Nantou (to the east). It is one of approximately 70 public halls built all around Taiwan to accommodate large public gatherings during the Japanese colonial era. This particular example was built in 1930 and is one of three remaining in Changhua. The other two—in Changhua City and Lukang—are both fully restored heritage properties open to the public, but this smaller hall has been derelict for years, a consequence of a long-running legal dispute between the landlord and local government complicating preservation efforts.

A closer look at the façade. The circular outline of where the original sign would have been mounted is visible. You may also notice a moth in the frame; there were hundreds flying all around the building when I visited.

The grounds were not well-kept when I visited in 2017.

The characters emblazoned on the front of the building read Zhōngshān Hall (中山堂)¹ but this was not the original name. If you look closely at the photograph you can see a circular outline around the central character, almost certainly where something would have been mounted. I strongly suspect this would have been a plate inscribed with the city emblem (市徽) for Ershui, a convention outlined in an entry about the nearby Fenyuan Village Office. I went looking for archival footage of the hall but found nothing online to confirm this hunch.

Creeping around the side of the derelict public hall.

The public hall² was constructed between the older, unplanned Qing dynasty era settlement and the newer, more modern area around Ershui Station (二水車站), which opened in 1905. This reflects a common urban planning pattern in the Japanese colonial era: grafting an area of wider streets (often on a grid) and institutional buildings onto an existing town³. This parcel of land was originally the site of the hall, a police station, and several wooden dormitories, among which the station chief’s remains intact. Google Street View records indicate the police station was still present in 2012 and only demolished after the lease on the land beneath it expired—so the unkempt meadowland immediately adjacent to the public hall has only been empty for a few years.

The side door is open for some reason, how could I not go take a look?

I didn’t expect to be able to take a peek inside the old hall, particularly not after jumping the fence around the side and arousing the attention of two Taiwanese men playing catch on a bare patch of ground next to the fire station, which is still in use. I inquired about taking a look inside and, after glancing at one another, the man closer to me gave me a curt nod. Stepping through the weeds, I went around back and had a look inside the public hall.

Inside the public hall. It doesn’t look so bad in here.

Evidently it is now used as storage by the fire department.

Unbeknownst to me at the time, the hall originally served as an office of the hokō system (保甲制度), a grassroots form of civic self-governance and law enforcement adapted from the pre-existing Qing dynasty baojia system. This system provided an interface between community leaders and law enforcement—which also explains the hall’s proximity to the colonial era police station. Community leaders under the hokō system were charged with registering overnight visitors, reporting suspicious activity, and other such duties.

The hokō system was also used to reshape social customs in the early Japanese colonial period. Foot binding, a common practice in late 19th century Taiwan, was viewed by the Japanese as an uncivilized custom (and rightly so). Seeking to discourage and then outright ban the practice in the 1910s, the Japanese sent orders down through the network of hokō offices to identify households with bound women and eventually order their unbinding⁴.

Behind the hall is an old wooden dormitory, the residence of the head of the nearby police station. Visually there is nothing too unusual about this structure, nor was there much of anything left inside. Most interesting is the flagpole stand positioned out front. It is constructed in the same rugged stone-washed style (洗石子) as the public hall, and seems to have been moved here when the neighboring police station was demolished.

The derelict public hall in the heart of Ershui.

Since publishing this article in early 2017 metal fencing has gone up around the site, and in 2019 the Changhua County government registered the Ershui Public Hall and Hokō Office as a historic building, subject to protection under the law. There are only so many old public halls left in Taiwan—the vast majority⁵ have already been destroyed—so this is very good news!

While exploring the public hall in May 2017 something else caught my eye: an eclipse of brightly-colored, iridescent moths flitting around the overgrown ruins—and many more locked in an embrace on whatever flat surfaces could be found. Evidently this area is a breeding ground for Taiwan’s only geometrid moth species, Milionia basalis pryeri, a subspecies of Milionia basalis only found in Taiwan and southwestern Japan, particularly Okinawa. There appears to be no English common name but in Chinese it is generally known as the orange-banded moth (橙帶枝尺蛾)⁶. Nature reclaims abandoned spaces in startling ways!

One last look at the front of the old Ershui Public Hall.

Despite hopeful signs in the wake of the heritage designation in 2019 the local government has had a difficult time coordinating with the landlord to restore the building, or at least prevent it from deteriorating further. By 2026 it was reported that the roof had completely collapsed, leaving the interior exposed to the elements.

After the Kuomintang arrived in Taiwan they enacted a policy of re-sinicization that involved—among other things—renaming major streets, buildings, parks, and sometimes entire settlements after various elements of party ideology. “Zhongshan” commemorates Sun Yat-sen, first president and founding father of the Republic of China, and pretty much every public hall in Taiwan was given this same, unimaginative name. ↩
I should probably mention that there appears to be no standard English translation of gōnghuìtáng (公會堂). I have used “public hall” but I have also seen “assembly hall”, “public assembly hall”, “public meeting hall”, “public auditorium”, “union hall”, and “guild hall” in use. ↩
This excellent post (in Chinese) contains more information about the urban development of Ershui. ↩
This paper argues for the importance of the sugar industry in decreasing the rate of foot binding in Taiwan. Economic opportunity and self-interest also played a role, in addition to official decrees. ↩
Only about a dozen public halls remain in Taiwan. If you’re interested in making a deep dive into this class of Japanese colonial relics I recommend a series of three posts documenting 22 public halls in northern Taiwan, 18 in central Taiwan, and 29 in southern Taiwan. Among these, the most famous and accessible remaining example is the Taipei Public Hall (臺北公會堂), now also known as Zhongshan Hall in Taipei. ↩
Naturally these strikingly beautiful moths have attracted the attention of Taiwanese bloggers; for more photos and info in Chinese try here, and here. More basic info can also be found here, here, and here (in Chinese) and here (Japanese). ↩

Series: Taiwan Summer Road Trip 2017

In the summer of 2017 I borrowed a scooter to ride to a music festival in Nantou and only returned it several months later. It wasn’t a continuous road trip—I’d leave the scooter parked at various HSR stations as I slowly made my way around central and southern Taiwan—but each leg of the trip usually involved 3 or 4 days of riding. In the end I gathered enough material for 60 or 70 posts, only some of which have been published.
