SHENYANG, Sept. 15 -- A centennial mansion-turned-museum in northeast China opened to the public at night to celebrate the Mid-Autumn Festival which fell on last Friday this year.

The museum, once the mansion of Marshal Zhang Zuolin (1875-1928) in Shenyang, capital of northeast China's Liaoning Province, extended its opening hours for the first time on Saturday for the public.

The museum was decorated with 120 red lanterns and a huge "moon" with an 8-meter diameter on the ground, with upgraded night lighting facilities. Visitors also received portable lanterns and mooncakes.

The mansion is the former office and residence of Zhang Zuolin and his son Zhang Xueliang (1901-2001), a former general of the Kuomintang party.

Built in 1914, it is the largest and most well-preserved former residence of celebrities in northeastern China. It was opened to the public as a museum in 1988.

The mansion was inscribed on the 20th century architecture heritage list of China in 2017.

"It is the first time for the museum to provide night tours since its opening to the public in 1988," said Zhao Jumei, the vice curator. "We hope that it will bring visitors a different experience."
