The two maps illustrate a comparison between what a museum’s south wing was like in 2008 and what it was like after development in 2012.
From the west to the east, there are a number of changes. The special collective gallery on the west end stayed unchanged. Replacing the original entrance, an entrance hall was built straight to the stairs. With a restaurant as an addition to the north side, the middle section was expanded. While the interactive gallery and the shop were the same as they were before, the gallery was developed into a dual-functional space with a cloak room. The east end was also expanded. Where the stairs were in 2008, there was an elevator instead in 2012. The space shared by a reading room and a cloak room was divided into two separate rooms—the reading room and a section designated for children replacing the cloak room. Next to the reading room was a self-service café, with an exhibition room still next to it.
Overall, the whole section of the museum changed markedly into a more versatile area.

Two routes 【遇到名词的时候，考虑有没有修饰/补充信息的可能性：同位语、从句、动词分词、形容词短语等形式】 , which lead to two assembly points, are available for evacuation when a fire happens. Meanwhile, tenants should use the two routes with caution: they should not go through the west-east corridor but use the nearest exits and.
Assembly Point 1 is located at the southwest corner of the dorm building, and it should be used by tenants in Bedrooms 1, 2, and 3. For tenants living in Bedrooms 1 and 2, they should go through the west corridor and use the stairs at the end to escape. Since Bedroom 3 is directly facing the stairs, residents in that room can go straight to the stairs and leave the building. Bedrooms 4, 5, 6 and 7 as well as the elevator are close to the other meeting point 【遇到名词的时候，考虑有没有修饰/补充信息的可能性：同位语、从句、动词分词、形容词短语等形式】 – Assembly Point 2, and residents and passengers should therefore use the east corridor and the corresponding stairs 【遇到名词的时候，考虑有没有修饰/补充信息的可能性：同位语、从句、动词分词、形容词短语等形式】 , adjacent to Bedroom 7 at the northeast corner, to reach that meeting point.
Overall, the evacuation stairs and meeting points are respectively easily accessible from the two sections of bedrooms and the elevator.
