The Liaota in Chaoyang City's Shuangta District has both a Heavenly Palace and an Earthly Palace

The twelfth floor of the thirteen-story dense-eave tower from the Liao Dynasty houses a Heavenly Palace, where a five-tiered treasure box and two sarira were discovered. Such claims about the sarira should be taken as stories. Inside the Earthly Palace, there is a scripture pillar over five meters tall. The real treasure among the cultural relics is this Persian glass bottle within a bottle, as shown in figure nine. I have a question: why didn't the British export glass to China in the 19th century?
