What are the most important ideas of Blue Ocean Strategy and practical examples from life?

Blue Ocean Strategy (BOS) was proposed by W. Chan Kim and Mauborgne.　The Blue Ocean Strategy argues that focusing on red oceans is tantamount to accepting the limiting factor of commercial warfare, i.e., winning on a limited amount of land, while denying the possibility of creating new markets in the business world. With Blue Ocean Strategy, one looks beyond the competitors to the needs of the buyers, crosses the existing competitive boundaries, sifts and reorders the elements of buyer value in different markets, and shifts from choosing to position oneself in a given structure to changing the structure of the market itself.　Blue Ocean takes Strategic Move as the unit of analysis, which consists of a set of management actions and decisions involved in major business projects to open up markets. Based on the study of 150 strategic moves in more than 30 industries from 1880 to 2000, it is pointed out that Value Innovation is the cornerstone of the Blue Ocean strategy. Value Innovation challenges the traditional competition-based dogma of value and cost trade-offs, allowing companies to integrate innovation with utility, price and cost, not to catch up with rivals by comparing to the best practices of the existing industry, but to change the industrial landscape to reset the rules of the game; not to aim at the "high end" or "low end" of the existing market; not to aim at the "high end" or "low end" of the existing market; not to aim at the "high end" or "low end" of the existing market. Instead of targeting "high-end" or "low-end" customers in the existing market, it is oriented to the potential demand of the buyer public; instead of segmenting the market to satisfy customer preferences, it is to merge the segments to integrate the demand.　A typical example of blue ocean strategy is Cirque du Soleil. In the circus industry, which is shrinking due to "animal protection", "supply-side bargaining of circus stars" and "buyer's bargaining of family entertainment competition", the traditional circus industry is shrinking, and the traditional circus industry is shrinking. In a shrinking circus industry, the company has shifted from the traditional circus audience of children to adults and business people, expressing the plot of the play in the form of a circus and attracting people to enjoy this unprecedented entertainment at a price several times higher than the traditional circus
