In fact, it is a signature. After writing a calligraphy work or painting a painting, if you feel it is good, leave a signature to prove that it is your own work. In foreign countries, names are mostly written directly, while in China, calligraphy, painting, and seals are used. In ancient times, we also paid attention to a trend, which dynasty was popular in what style of seal calligraphy and painting, the size of the style, the material of the seal, etc. Others are different depending on personal personality, author, collector's preferences, whether there is a model or not, and what models are available.

In addition, some collectors who get masterpieces or calligraphy and paintings that they like very much will add a symbol on the calligraphy and painting to prove that they own and collect it, so some calligraphy and paintings will have different people on them. There are different styles and multiple seals. This is called the collection and appreciation seal. Most of the seals will have the words collection, appreciation, and treasure on them.

The seals are also very particular, with different materials, such as Huangtian stone, metal, wood, stone, jade, etc.

The shapes and fonts are also different, some are square and round, some are strange, some are square and some are full of fun.

There is also a lot of content. Most of the seals are names and titles, and some are poems and idioms.

Generally speaking, the style of calligraphy and painting can mostly prove the author. This is also one direction for judging the authenticity of many paintings and calligraphy. There are also many paintings with no words at home and abroad, which means that the authenticity can only be judged from other directions, such as Paper, painting style, font, ink, etc.

The other thing is that I am learning to draw, and there are a few of them that I just like and have fun with.
