Hall of Union (Jiaotaidian) Ⅱ

In Qing Dynasty, there were 25 treasured and authorized seals preserved in this hall, and each seal had a special use. In first lunar month of each year, the special official would select a good day to show these treasures and emperor also came here to show respects. Additionally, there was a standing iron board with Chinese characters” 内宫不许干预政事”( The empress, concubines, and eunuchs living and working in Forbidden City could not interfere into the national affairs). In spring each year, there used to be a ceremony or rite for sacrificing to silkworm at Jiaotaidian (Hall of Union) , and empress at the day before the ceremony would be here to check the tools of picking leaves of mulberry.
