Blank space is an important technique in Chinese artistic creation, which also reflects the development ideas and wisdom. Just as the blank space in art can create infinite meaning in limited space, the blank space in development can also expand and enrich the connotation of the city. Many old urban areas in big cities have limited space for industrial development. If we don't reject anyone, 'picking up vegetables in the basket' can easily lead to disorderly development and overdrawn the future. And some places consciously "leave blank spaces" for future development, attracting high-quality projects and emerging industries, "keeping the clouds open and seeing the moon shining". At present, many cities, including Beijing, Shanghai, Qingdao, etc., have designated blank land and introduced management measures, reflecting a change in the concept and path of promoting development. Reserving space for sustainable development and leaving a beautiful home with blue sky, green earth, and clear water for future generations is a forward-looking thinking and long-term vision. General Secretary Xi Jinping pointed out that "the construction of Xiong'an New Area is not something that can be done in a day or two. It cannot be done all at once. It is necessary to leave blank spaces and room for future planning by reserving projects and plots." "Green mountains and clear waters are like mountains of gold and silver, and Xiong'an New Area relies on such an ecological environment to reflect its value and increase its attractiveness. Nowadays, the forest coverage rate in Xiong'an New Area has increased to 35%. More than 20 million saplings of Pinus tabulaeformis, Sophora japonica, and Paracel have grown into a continuous forest sea. A central green valley with a length of 7 kilometers from north to south and a span of 3.2 kilometers from east to west connects the ecological network of the city, vividly depicting the construction concept of "planting green first, building the city later" and "people's city for the people". Leaving blank space is not about doing nothing, but planning before taking action; It's not about not pursuing development, but about seizing opportunities and striving to achieve higher levels of development. Take the implementation of the development strategy of the Yangtze River Economic Belt as an example. At the beginning, General Secretary Xi Jinping emphasized the need to adhere to the principle of jointly safeguarding and not engaging in large-scale development. The ecological environment has been well protected, and the beautiful scenery of "one river flowing eastward" has reappeared. The overall recovery trend of aquatic biological resources has improved, consolidating the foundation for high-quality development of the Yangtze River Economic Belt. For example, the Ganhe Industrial Park in Xining, Qinghai has eliminated various "small scattered" and high energy consuming and high emission enterprises, seized the opportunity of "dual carbon", laid out emerging industries such as new materials and new energy, and focused on building a highland of green energy. It has become a microcosm of Qinghai's major mission of maintaining ecological security and cultivating a modern industrial system that reflects local characteristics and advantages. Find the positioning in the overall situation, think about the development path beyond the gains and losses of "one city, one place", clarify the direction and focus with "doing something", and guard the bottom line and boundaries with "not doing something", achieving a sense of basis for advance and retreat, and a strategic vision behind it. The techniques of "Chinese painting" include splashing ink and color, as well as outlining and dyeing. Where to write and where to leave blank spaces, the key is to start from the overall and practical aspects, adapt to the situation according to the time and circumstances, and act according to the rules. Focus on safety production in key areas, without leaving any blind spots or loopholes. For new technologies, industries, formats, and models, it is necessary to implement and improve inclusive and prudent supervision, leaving enough room for development while adhering to the bottom line of quality and safety. The Suzhou Humble Administrator's Garden is praised for its exquisite "Borrowing the Scenery of the North Temple Pagoda": Looking into the distance from the Rainbow Pavilion, half of the pagoda's body is exposed among the ancient trees and willows, resembling a Buddhist pagoda in the garden. This landscape cannot be separated from Suzhou's efforts to protect the overall style of the ancient city through measures such as building restrictions, showcasing the charm of "leaving blank space" in the "double-sided embroidery" of economic prosperity and cultural prosperity. There are more ideas and methods to draw rich nutrition from the excellent traditional Chinese culture and promote Chinese path to modernization. (New Society)
