An Englishman named Wilson Harrell came to the United States in the early 60s, and after settling down, he bought a small company that made cleaning liquid, and started operating a cleaning solution called "Formula 409". By 1967, "Formula 409" had captured 5% of the U.S. detergent product market and obtained a monopoly right.

Just as Harrell was about to fully expand the "Formula 409" cleaning solution in the United States, he suddenly encountered a strong competitor - the American company Baoso. The company has a long history and strong strength, and its production of "ivory soap" is famous in the United States. Later, they introduced the Hassle Saver cleaning solution, which gave Harrell's "Formula 409" a serious challenge.

This time, the company is determined to defeat Harrell. They have invested more money than "ivory soap" in naming, packaging and promoting "novelty" products, making costly market forecasts and advertising campaigns. Because they have a strong foundation and sufficient funds, they are full of confidence.

But things are not absolute, and there are downsides to the scale. Harrell judged that the company would not pay close attention to his actions because of self-confidence. So he took advantage of the flexibility and quick action of the small company to start a guerrilla war with the Baoda Company.

On the one hand, Harrell stepped up the improvement of the packaging and color of "Formula 409" to confuse the other party, and on the other hand, sent a reconnaissance team to search for the opponent's intelligence and market forecasts. When he found out that Denver, the company's competitive location, had been selected as the first test market, Harrell took advantage of the small company's quick withdrawal and cleverly removed Formula 409 cleaning solution from Denver. Of course, it is not to remove all the goods from the market shelves, but to suspend all promotions. The main reason for this is to prevent it from being discovered by the company.

This trick really worked, and the "novelty" cleaning liquid became a bestseller for a while, and the members of the test sales team of Baoda Company were very happy about it. The news reached the company's headquarters, which was also triumphant, and immediately decided to put more "novelty" cleaning liquid into the city of Denver.

Just when the whole company was jubilant, Harrell took decisive revenge for the survival of the company. He took advantage of the large influx of "novelty" cleaning liquids into Denver, and took the opportunity of testing the market in Denver to start a price cutting war, selling the "Formula 409" on the market shelves at a preferential price. Although there were not many goods left in Denver, it was enough for cheap consumers to buy about a year's supply at a time, and by the time Bao Soda sent an army to Denver to promote the "novelty" cleaning solution, the person in charge of market testing had not allowed them to sell at a high price. Even if the price comes down, it will be too late, and "Formula 409" has already taken root in the hearts of the people. Here Harrell used the strategy of Li Dai Taozhuang, abandoning the small and taking the big, and achieved a great victory.
