Is it reliable to buy Nie Weiyong's calligraphy and painting online?

Not reliable.

Nie's calligraphy and paintings can be purchased offline in galleries and art exhibitions. Buying Nie's calligraphy and painting online is risky, because it is impossible to determine the authenticity and preservation of the works.
