Modern history, in situ
Where Northeast China's ports, banks and post began
- Liaohe Old Street: 1.3km of treaty-port architecture, free to wander — an open-air museum of the era
- Verified century-old firms: Dongji Bank (1924, once partnered with HSBC), Xieshengfeng (1904), Yonghexiang oil mill (1921), Yuanxingcheng/Yitai (c.1904)
- The West Fort: an 1882 Qing coastal battery, the Northeast's largest rammed-earth sea defense, now a National Key Heritage Site
- In 1878 Yingkou (Niuzhuang) was among Li Hongzhang's five pilot post offices — a cradle of China's modern mail
