On April 26-29, 2018, the 27th Hotelex (Phase II) was held at Shanghai New International Expo Center. The debut of Sidefu brand has become one of the biggest attractions in the hotel's linen area. The theme of the ink and wash design ignited the fashion of hotel linen. The viewers stop and ask,and they all liked it. The theme is inspired by the ecological scenery of the towns, using the combination of black, white, and gray colors, dots, lines, and surfaces to organically combine the exhibition area, exhibits, and themes. The traditional classics are stylish, magnificent and introverted, cleverly fits the culture of Confucianism and Dao. It reveals the harmony between man and nature, just as the theme of the work interprets: the good is water, the ink is like a man, the Confucian is a mediocrity, and the Tao is natural.
