The history textbook should introduce the pointed bottom bottle. In the textbook, the pointed bottom bottle is a water pump. Now, this statement is still one of the statements that have been determined as standards. However, in 1988, an experiment broke the saying that it has been said for decades and has been set as a standard. Through experiments, we found it difficult to draw water from a pointed bottom bottle. (Of course, this experiment is interested in specific data, which can be found on the Internet. ) In any state of water flow, a pointed bottom bottle is not suitable for drawing water.

After the use of the pointed bottom bottle as a water receiver was overturned, the two went on to suggest that the pointed bottom bottle was an ancient water receiver. However, this guess has also been overturned, because the pointed bottom bottle, as a water reservoir, is not as easy to use as a bucket, nor is it as easy to put on the ground as a bucket.

Later, some people put forward a variety of speculations about the use of pointed-bottom bottles, such as the Ming vessels used by the Zhou Dynasty to warn future generations. But this statement obviously does not conform to the setting of funerary wares in history books. Ming wares in history books are used by nobles to warn future generations, obviously not by ordinary people. However, pointed-bottomed bottles have appeared too many times and are one of the most common relics in ruins, so this statement is not recognized by many people.

Some people say that the sharp-bottomed bottle is a funerary object, but this statement has also been overturned, saying that the sharp-bottomed bottle is a funerary object, mainly because ancient children are not qualified to be coffins. But this view was later overturned by the appearance of mermaid pottery basin, because mermaid pottery basin is the lid of children's urn and coffin. The difference between a fish-faced pottery basin and a bottle with a sharp bottom is that the fish-faced pottery basin is not sharp and can be placed on the flat ground. Of course, no matter what the final result is, if one of the above statements can overthrow the water pump mentioned in the history textbook.

Second: Qin bamboo slips

Qin bamboo slips, as a classic case of Historical Records, have to be said here. The appearance of Qin bamboo slips directly overthrew the statement about Qin in Historical Records. For example, the strictness of Qin law. As we all know, Guangwu, Chen Sheng, Guangwu and Chen Sheng uprisings are most typical when Guangwu and Chen Sheng failed to arrive at the service place on time due to heavy rain. Chen Sheng and Guangwu were afraid of being beheaded, so there was Chen Sheng and Guangwu Uprising. However, it is not described in Qin Law. In the Qin law, there is no risk of beheading because of natural factors, only 20 sticks. The excavation of Qin law directly overthrew Sima Qian's harsh statement in Historical Records.
