The first time I came to this shopping mall~ [Environment] To be honest, I felt normal when I came out of the parking lot, because many customers couldn't find the elevator to enter the mall in the parking lot. The sign was not clear~ The mall was popular and there were not many customers~ But at the moment I entered the toilet, I felt the senses of the mall. The parent-child toilet is particularly loving (Figure 2), the layout and facilities are very loving, the details are particularly in place to see the merchants' intentions~
