The Mausoleum of Narsu is situated east of Tianshou Village, Tangfang Village, Liushutun Township. It is the burial ground of Narsu, Prince Cheng Shen of the Mongolian nobility in the Qing Dynasty.

Constructed in the late Qing Dynasty, the mausoleum was started in 1887 and completed in 1890. Its original name was Xiaojie Mausoleum, commonly known as the Rear Mausoleum. It was designated as a county-level cultural relic protection unit by the People’s Government of Kangping County in 1990. On October 27, 2008, the People’s Government of Shenyang listed it among the third batch of municipal-level cultural relic protection units.

The mausoleum stretches 112.5 metres from north to south and 53 metres from east to west, covering an area of 5,962.5 square metres, which is defined as the core protected zone. In addition, the construction control zone covers the area bounded by the highway in the south, 100 metres east beyond the mausoleum wall, 300 metres north beyond the wall, and 20 metres west beyond the wall. No new construction is permitted within this zone.

Originally, the complex contained six side halls each on the east and west, three middle halls, and surrounding walls, together with more than 150 ancient pine trees inside and outside the compound. Today, only the middle hall and sections of the boundary wall remain. The roof of the middle hall has been rebuilt into a flat roof. Most bricks and tiles have fallen off the mausoleum wall, though the foundation traces of the east and west side halls are still clearly visible. Only 21 ancient pine trees survive today.

The tomb was robbed and destroyed around 1947 during the land reform. A great number of precious cultural relics were unearthed and all sold off at that time.

This is the only remaining Qing Dynasty mausoleum in the county. It bears great significance for researching the lineage, branches and history of the Horchin Mongolian clan
