Figure 3 shows the tomb. The tomb is an excavation tomb. According to the depth analysis of scattered tomb bricks and tombs, the owner's identity is relatively high. Only two or three pictures can definitely not tell that it is Cao Pi's tomb. Only according to unearthed cultural relics and literature records can we make a general judgment.

Figure 4 shows a tomb of another period (the brick shape of the tomb is different from Figure 3), which can be traced back to the Sui Dynasty. The owner of the tomb may be a local squire (shallow tomb).

Figure 5 shows the firing history of rope brick, which began in Qin and Han Dynasties and ended in Song Dynasty. The general law of dating is that the earlier the age, the larger the brick type, the finer the rope pattern and the later the age. Only by analogy based on scientific archaeological data can we accurately determine the age of ancient bricks.

To confirm whether it is Cao Pi's tomb, it is best to get in touch with the archaeologists at that time, who have first-hand information. According to analysis, unlike imperial tombs, imperial tombs are generally paved with ancient brick steps.

As long as there are no bad intentions, there must be enough evidence to prove that it is Cao Pi's tomb.
