📜 Historical Evolution: A Thousand-Year-Old Thermal Spring with Imperial Origins

Tanggangzi Hot Springs is one of China’s oldest and best-documented medical hot springs, with development dating back to the Liao Dynasty (10th–12th centuries):

• 🏯 Liao and Jin Dynasties: Already known to Khitan nobility; the History of the Liao Dynasty – Geography Chapter records “Anzhuo Prefecture has hot springs,” referring to the present-day Tanggangzi area. During the Jin Dynasty, a “Tangchi Post Station” was established, serving as a key node along the Liao Dong postal route.
• 🐉 Qing Dynasty Peak: Both Emperor Kangxi and Emperor Qianlong stayed at Tanggangzi during their eastern tours. Emperor Qianlong personally inscribed the plaque “Lingquan” (Spiritual Spring), original now lost—only a restored stone tablet remains in the hot spring sanatorium. In the Guangxu era, Shengjing General Yiketang’a petitioned the court to establish the “Tanggangzi Official Hot Spring Bureau,” dedicated exclusively to managing and applying the therapeutic waters.
• ⚙️ Modern Transformation: In 1911, the South Manchuria Railway Company built Asia’s first modern hot spring health resort—the “Mantetsu Tanggangzi Hot Spring Sanatorium”—introducing German hydrotherapy techniques and X-ray diagnostic equipment, laying the foundation for modern Chinese thermal medicine.
• 🇨🇳 New China Era: Nationalized in 1950 and renamed “Tanggangzi Hot Spring Sanatorium,” it became one of the country’s first designated key rehabilitation institutions. In 1987, it was listed by the State Council as a National Key Hot Spring Rehabilitation Base.

✅ Authoritative Evidence: The Chinese Mineral Water Gazetteer, Compilation of Northeast Local Chronicles, and Anshan City Annals – Health Volume all detail its historical trajectory. In 2013, “Traditional Therapeutic Techniques of Tanggangzi Hot Springs” was included in the Anshan City Intangible Cultural Heritage List.

🏛️ Architecture & Archaeological Remains: A Unique Ensemble of Sino-Western Spa Structures

The site preserves three core historical architectural complexes, combining modern industrial heritage with regional cultural significance:

1. Mantetsu-era Buildings (1911–1945)

• Main Building (now the Outpatient Department of Tanggangzi Hot Spring Sanatorium): Brick-concrete structure in eclectic style, featuring red-brick façades and gray slate eaves. Houses century-old cast-iron ventilation ducts and original thermal water circulation systems.
• Former Open-Air Carbonate Bath Pools: Features well-preserved granite pool foundations and drainage channels—rare examples of early open-air carbonate bath facilities still intact in China.
• Former Therapy Pavilion: Contains an original German “Hermann von Helmholtz” hydraulic massage tub imported in 1928; now recognized as a Provincial Immovable Cultural Relic (No. LN-LDQ-027).

2. Qing Dynasty Remains

• Dragon King Temple Ruins: Located north of the spring source, preserving a stele from the 23rd year of Daoguang (1843), inscribed with text stating: “The hot spring gushes forth abundantly, curing rheumatism and illness—villagers annually worship the Dragon God in gratitude.”
• Ancient Spring Well Stone Platform: Constructed from green stone, 1.2 meters in diameter, with a Qing-era iron “Fu” (Blessing) plate covering the spring outlet (currently housed in the site museum).

3. Representative New China-era Architecture

• Rehabilitation Building (1954): Soviet-style design with red tile roofs, housing China’s first independently designed “stepped thermal water therapy corridor,” symbolizing early post-founding medical infrastructure achievements.

💧 Geology & Water Quality: Naturally Medical-Grade Bicarbonate Sodium Spring

Tanggangzi Hot Springs belong to a deep fault-zone confined self-flowing thermal spring system, formed by tectonic activity in the Liao Dong rift zone and geothermal energy from Precambrian metamorphic rock basement:

| Indicator | Value | Medical Significance | |------------------|------------------------------------|-----------------------------------------------------------| | Water Temperature | 68–72°C (consistently stable year-round) | Ideal for full-body immersion and heat therapy | | Daily Flow Rate | ~2,400 m³ | One of China’s largest single-point medical hot springs | | Primary Components | Bicarbonate sodium (NaHCO₃), fluoride, silicic acid, lithium, strontium | ✅ Improves rheumatic and immune disorders<br>✅ Promotes bone metabolism and skin regeneration<br>✅ Regulates nervous system function | | Radioactivity | Trace radon (Rn): 22–28 Bq/L | Meets the medical thermal mineral water limit in GB/T 13727-2016 Natural Mineral Water Standard |

🌟 Scientific Certification: In 2021, testing by the Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences, confirmed it as Grade I Medical Thermal Mineral Water (Certificate No.: ZK-2021-TG001).

🏯 Cultural Value: A Living Testament to Northeastern Hot Spring Civilization

• Medical and Humanistic Significance: Pioneered China’s practice of “thermal preventive medicine,” establishing a traditional four-method therapy system—bathing, drinking, inhalation, and topical application—whose influence extended to regions like Changbai Mountains and Wudalianchi.
• Industrial Heritage Value: The Mantetsu Sanatorium stands as key physical evidence of modern thermal medicine industrialization in East Asia, reflecting dual dimensions of Sino-Japanese technological exchange and colonial medical history.
• Regional Cultural Symbol: The name “Tanggangzi” appears in Records of Liao Dong and Comprehensive Gazetteer of Fengtian. Folk wisdom holds the saying “Three days soaking in the spring equals ten years of ginseng,” giving rise to customs such as spring rituals and winter bathing ceremonies on the Winter Solstice.

🌿 Special Note

Tanggangzi Hot Springs is not a typical tourist bathing facility—its core value lies in its medical rehabilitation function and historical authenticity. Visitors are expected to respect treatment protocols, refrain from climbing on relics, and avoid photographing patient treatment areas.
