However, whether Yao Gannan's calligraphy is valuable depends not on his professional background and achievements, but on the quality, artistic value and market demand of his calligraphy works. If his calligraphy works have high artistic value and market demand, then his calligraphy may be valuable. On the contrary, if his calligraphy works are of average quality or not recognized by the market, then his calligraphy is not necessarily valuable.
Therefore, to evaluate whether Yao Gannan's calligraphy is valuable, we should not only analyze and evaluate his calligraphy works in detail, but also consider the relationship between supply and demand in the market.
