When Toshio Kou first started running the "Kou Pharmacy", his business was very light and he could barely make ends meet.

Poor and bored, reading books to get by. Days like this, until he saw a book. The book is called "Japan's Attack on the Mainland." It is written about the Japanese attack on China during World War II.

The invading Japanese army occupied only cities in Chinese mainland, and the cities were connected by lines of communication protected by troops, and the vast countryside was still controlled by the anti-Japanese army and civilians. Once a point of these lines of communication is encircled and breached, the lines of communication of the occupying forces will be cut off, leaving the city in a predicament of being vulnerable to the enemy, which is extremely easy to breach.

Looking at it, the inspiration in Duiyongkou's heart was stimulated: in business, isn't it possible to use it for the above situation?

Suppose there are three small shops that are not in a straight line, and their geographical location is on the three vertices of a triangle, and the lines between them form a triangle.

If these three small stores are operated by the same leader, maintain close contact with each other, and form a chain form, then any one of the stores is out of stock of a certain drug, as long as a phone call is made to two nearby stores, they will immediately receive support. Any small store will make customers feel that the medicine is abundant and available.

Medicines are a special commodity with uniform quality standards, and once needed, there must be a sense of urgency, and as far as possible, they should be purchased as close as possible, regardless of whether the pharmacy is dignified or not.

Consumers in the triangle are in a state of being surrounded, "there is no way out", they will definitely buy in this triangle chain store system, these three small stores will have a larger coverage, and it is strange that business is not good!

From then on, he was hospitable and thrifty, and with a little savings, he bought two small shops in the neighborhood, and the first triangular chain was finally formed.

Soon, the triangular business method of the mouth exerted its surprising power. In addition to what he had originally predicted, he also found that advertising in any one of the triangular chains meant that the other two stores were also advertising. Moreover, the three stores can purchase together together, so that the purchase cost can be reduced if the purchase volume is more, and the ability to compete in price will be enhanced. Coupled with the full range of goods, timely transfer of goods, and good service attitude, the business of the pharmacy is thriving.

Not satisfied, he went on to develop his triangular business method. Based on any two old stores, develop a new store so that the three stores form a new triangular chain system.

Thanks to the support of the two old stores, the new store is just as strong as the old one. In this way, every time a new store is built, a new coverage can be expanded, a coverage that can be effectively controlled and that competitors can't enter!

Soon after, he established a chain of pharmaceutical stores, and he expanded his business to the whole country, and chain stores appeared all over Japan one after another. In 1981, the number of chain stores in the mouth grew to 512, and there is a great momentum of continuous growth. In 1987, its sales accounted for 11% of all pharmaceutical sales in Japan.

The triangular management method of the mouth is the flexible application of the "closing the door and catching the thief" strategy in the operation.

The past is used for the present, and it is still infinitely powerful.
