Some twenty auxiliary tombs, probably holding the remains of the emperor's councilors and retainers, were discovered in four locations. One is in the northern part of the city itself and features twenty-eight small or medium sized burials. Another is in the western section between the walls, while others are scattered in the eastern and western sections outside the wall. These auxiliary tombs also hold the remains of princes and princesses killed by Hu Hai, the second son the Emperor Qin, after he usurped the throne. He condemned his siblings to death on the pretext of "accompanying their father".

The largest auxiliary tomb is that of Prince Gao, one of the sons of Qin Shi Huang. It is claimed the prince said he would rather die than ascend the throne. His tomb was found in the western section. The interior tomb measures 15.5 meters in length and 14.5 meters in width, with a 15.8 meter entry pathway. It was said also that Prince Gao requested to be buried near his father.

The seventeen tombs, neatly arranged from north to south found in Shangjiao Village attracted great attention. Eight tombs excavated in 1976 yielded two hundred pieces of gold and silver, as well as bronze and iron articles inscribed with words such as "Shao Fu" (Young Master's Mansion) or "Rong Lu" (Honor and Fortune). The objects indicate that these tombs held the remains the royal siblings of Huhai.

Also near Taochitou village and Zhaobeihou village, other auxilitary tombs were found.

A hundred tombs were excavated in 1978 and revealed the skeletal remains of one hundred people, but failed to yield coffins or other objects. Inscriptions show that nineteen of those entombed were slaves from the six conquered states.
