What caught my attention first was 2．, that is, making images out of paper. It was difficult, but a lot of fun! With help from the artist, I 3． to make one in the shape of a fish. Then I went into a section decorated 4． a traditional Chinese study, with two beautiful Chinese paintings of a pine tree and some bamboo hung 5．. There was also an old man writing Chinese calligraphy: his writing was so free and elegant!

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
