After 1930s, Haiyuan Pavilion experienced wars, buildings were damaged, and treasures were scattered. Only a few of them were transferred to the National Library and Shandong Provincial Library. The party and government attach great importance to Haiyuan Pavilion. As early as June 1947, when Liaocheng was liberated, a certain department of the Eighth Route Army issued three orders to enter the city, and the second one was to "protect Haiyuange Library, one of the four major bibliophiles in China". 1June, 956, the people's government of Shandong Province listed Haiyuan Pavilion as the first batch of provincial key cultural relics protection units. In order to promote national culture and promote opening to the outside world, Liaocheng Municipal Government raised huge sum of money to repair Haiyuan Pavilion on June 1992+00. The rebuilt building is located in the original site. Because it is an old system, it has a single eaves and two floors, blue bricks and gray tiles, and red paint beams and columns. Both the main house and the matching house are made of brick-wood structure, with a mansion in front and steps in the back, and wooden lattice doors and windows, which have a strong architectural style of quadrangles in northern China in Qing Dynasty.
