During the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout.

As a new salesman, don't rush out to find customers. First of all, it is also the most basic thing to have a comprehensive understanding of the attributes of the products to be promoted, and to have an understanding of any aspect and information about the products. At the same time, we should have a familiar process with the company's work flow and understand the company's sales and operation system. Only by mastering these can we well introduce the company's products to our customers, and only when we encounter relevant problems in the marketing process can we know how to solve them, so as not to be in a hurry and affect our customers' confidence in the company. Therefore, sharpening knives does not miss woodcutters, and when they are fully prepared to find customers, the results will definitely be different.
