People are used to comparing the merger between enterprises to "fish eat fish". The merger between enterprises can be divided into three stages: one is "big fish eat small fish", that is, large enterprises merge small enterprises; Then there is "quick fish eat slow fish", that is, capital moves closer to technology, and new technology enterprises merge traditional industries; Then there is "sharks eat sharks", that is, "strong alliance" Haier people believe that they eat neither small fish nor slow fish, let alone sharks, but "Huck fish". Zhang Ruimin's explanation of "Huck Fish" is that the fish's body has not rotted, indicating that the hardware of the enterprise is very good; The fish is in a state of shock, which shows that there is something wrong with the enterprise's ideological concept, which leads to the stagnation of the enterprise. Once such enterprises are injected with new management ideas and have a set of effective management methods, they will be activated soon.
