It's not a simple matter to buy famous calligraphy and paintings. You should know how to evaluate the price of calligraphy and paintings. Because only when you know how to evaluate the price of calligraphy and painting, you won't waste money in collecting things. So how to correctly evaluate the purchase of celebrity calligraphy and paintings? Generally, we should consider the following four aspects:

1.字画所处的社会状态。字画处在经济繁荣的社会状态时就高，反之就便宜。收藏者综合状态好时就比不好时要价高得多。

1. The social status of calligraphy and painting. Calligraphy and painting are high when they are in a prosperous society, otherwise they are cheap. The price of collectors is much higher when they are in good condition than when they are not.
                

2.字画作品本身的艺术价值和历史价值，而且不受尺幅限制。当前社会上有一种说法认为尺幅大的字画就值钱，这个论点很荒谬。

2. The artistic value and historical value of calligraphy and painting works are not limited by size. At present, there is a saying in society that calligraphy and painting with a large scale are valuable. This argument is ridiculous.

3.字画是否珍惜。高水平字画艺术家的作品传世越少越贵，所谓"黄金有价艺无价"就是这个道理。

3. Whether calligraphy and painting are treasured. The less the works of high-level calligraphy and painting artists are handed down, the more expensive they are. This is the reason why "gold is valuable and art is priceless".

4.字画的艺术水平。买字画不是买白菜、萝卜挑个大的就好，好的字画不一定就尺幅很大，有些佚名的古代字画作品由于本身的艺术价值和历史价值很高，也很值得收藏。

4. The artistic level of calligraphy and painting. To buy calligraphy and painting is not to buy cabbage or radish. A good calligraphy and painting does not necessarily have a large scale. Some anonymous ancient calligraphy and painting works are also worth collecting because of their high artistic and historical value.
