When Cixi fled to the west, she borrowed a huge sum of money from Cao's courtyard and mortgaged it with only a small object. What is this?

A French tribute handicraft named "golden locomotive clock", however, this is not a "small object". It is said that it weighs more than 40 kilograms and is a pure "big" object! Cixi got * * * 300,000 taels of silver with this handicraft.

It is said that this "locomotive" still has some origins, and it has been some years. It is said that it was a gift from the French angel to Qianlong when he was in power. Gan Long likes this gift very much and will take it out to play for a while when he is free.

Let's talk about materials first. This clock is made of precious metals such as gold and platinum, so the quality is naturally great. Apart from its function, this thing is called a clock, but telling the time is just one of its many functions. In addition, this clock fully demonstrated and utilized the most advanced industrial technology at that time.

The gold locomotive clock, though light in weight, is quite flexible. The clockwork device can not only support the movement of the clock, but also make the train run on the designated track.

Even more amazing is that there is a cylinder on the train. After the hot water is poured in, it is transformed into heat energy by the mechanical energy inside the train, so that steam emerges from the chimney of the train, which looks like a real train from a distance.

In addition, there is a barometer near the train, which is actually a hygrometer. It predicts the weather through the change of humidity. Of course, it won't be too accurate, but it was amazing for people at that time.

Such a multifunctional clock makes Qianlong fondle admiringly. Later, it was in the hands of Cixi, and Cixi also liked it. Only later, because the Cao family sold hundreds of thousands of taels of silver, Cixi couldn't bear it, so she reluctantly gave this golden locomotive clock to the Cao family.
