Ruler Exiting the Pavilion
Scholars have said that seeing a ruler exit a pavilion or similar place of authority indicates a loss of part of their power. If these structures are folded, it may signify the complete loss of their authority or the end of their life. Furthermore, a dome may be interpreted as a woman, where the phrase 'erecting a dome' refers to marriage and consummating the marriage.
