1. quality of works: the value of calligraphy works is closely related to quality. It is necessary to evaluate the level of Wang's calligraphy works from three aspects: technique, artistic conception and pen use.
2. Market demand: The collection market of calligraphy works is very wide, but not all works have the same market demand. We need to consider the popularity and demand of Wang's calligraphy works in the market.
3. Work background: Understanding Wang's background and experience can help us better understand his works and values. For example, Wang was born in Ningjin County, Shandong Province.
