I wonder when this porcelain was made.

This is a high-fidelity jar wrapped in blue and white and twigs, which was made in the late Qing Dynasty and the Republic of China. There are many hi-fi speakers, and yours is one of them. The price of a single hi-fi speaker is not high, but the price of a whole hi-fi speaker is very high. This kind of porcelain is rarely copied; yours is genuine. thank you
