How much is saffron in China?

Could you please clarify the current market price of saffron in China? I'm particularly interested in understanding if there have been any recent fluctuations in its value, and what factors might be contributing to any changes. Additionally, I'd like to know if there are any regional differences in pricing, as well as the general quality and purity of saffron available in the Chinese market. Ultimately, I'm seeking a comprehensive overview of the saffron market in China, including its current status and any trends that may be emerging.
