The imperial territory of 40,000 Li has never been unified since Igu.
Fifty years of sacred life, 9,950 years from now.
The first part refers to that after the Qing Dynasty unified the whole country, it started from Qinling Mountains in the west, bordering the sea in the east, reaching Xing 'an Mountains in the north and the South China Sea in the south, with an unprecedented territory of 40,000 miles. The bottom line is that 50th birthday plus 9950 years old is exactly the same as long live.
