It is a misperception that the slits are complex, most of which are related to the handling of paints in the production process and the preservation of the environment at a later stage, and that their appearance is an incremental process that cannot be accurate until the day of the hundred years, when it is a scientific and objective argument that they increase over time. The ancient piano produced by the republic is also broken in historical terms. Some of the traditional processes are more important than the fact that they are not finished, and it is very important to analyse the prototypes to identify them. Hypocrisies are made and many methods are available, such as roasting with a fire and defusing it with ice and ice; painting with protein penetration into the ash, then steaming it, then drying the wind; or roasting with plaster. In fact, the difference between the slitting and the slitting is still great. The slits flow smoothly, with their tails disappearing naturally, and the slits like blade blades, while the slits go through processes such as cold-hot catalyzing or knife stabbings, which inevitably break and break. The engraving of the old genre is also an important basis for authentication. The backs are engraved, while the abdomen are engraved and written, and the blades are easily preserved, and the ink is more difficult to read if it is long. There are no signs of retortment within the abdomen, such as the adhesion of the upper and lower sides of the body, most of which are original, and which require careful study if they are found. The most difficult to recognize are the retreading of the old piano, which binds it and makes it seamlessly and when it is made from old wood. Regardless of the abdomen, the senior expert can also be identified by the common name of the ancient king's year, by the use of words to hide it, and by a bookwind of a dynasty or a calligrapher. A collector whose main purpose is to play must have one of the main criteria of the sound of the piano. We listen to the sound of an old piano, it's thick, it's bright, it's smooth, it's sharp, it's sharp, it's beautiful. In some cases, there are broken marks and “brakes” appear when the sound is played, affecting the hearing, at which point the gains and losses are carefully weighed and not simply discarded. The collection of ancient pianos usually chooses dry walls rather than flat over a long period of time; because of the laxity of the ancients, it can easily cause “fallbacks” over a long period of time, while modern, new-made old pianos do not have to be hung, and quality-quality pianos do not collapse for decades. Palaeon should often be played as a musical instrument, otherwise it can be dark, dark and infested with worms。
