Shanghai Museum, rich in collections and treasures, the exhibition area is large, is a world-famous large-scale museum. Some time ago, I visited the Shanghai Museum and the Asian Civilization Museum in Singapore jointly organized a large special exhibition "Baoli Fengwu - Blackstone Shipwreck Out of Water Treasures Exhibition". There are many treasures, today sharing the gold in the treasures of the Blackstone shipwreck, the material purity is high, the production process is exquisite, reflecting the high smelting technology, forging technology and design level at that time, is a rare treasure. From the perspective of shape pattern, it should be the work of the craftsman in the Tang Dynasty of China.
