Which forms of art flourished during Qianlong’s reign?

During the reign of the Qianlong emperor, the arts experienced a final period of brilliance, continuing the flourishing traditions established under his predecessors, the Kangxi and Yongzheng emperors. Several forms of art and craftsmanship reached high levels of development during this era:1

• Architecture: Qianlong invested heavily in the beautification of the Yuanmingyuan, expanding the estate with new pavilions, lakes, and gardens. He also commissioned Jesuit missionaries to construct residences and gardens that blended Italian Baroque and Rococo styles with traditional Chinese roofs.1
• Decorative Arts: The production of jade and ivory work flourished, reaching a peak of refinement.1
• Porcelain: The production of porcelain continued with great delicacy, particularly famille rose wares. Artisans were also challenged to create porcelain imitations of other materials, such as archaic bronzes, gold, and jade.2
• Painting and Calligraphy: Qianlong himself practiced these arts and was a significant patron, notably supporting the work of European missionaries at court, such as Giuseppe Castiglione and Jean-Denis Attiret.1

Additionally, Qianlong sponsored the Sikuquanshu, a massive compilation of Chinese classics, though this literary contribution was accompanied by strict censorship of works deemed seditious.1
