In traditional industries, marketing talents are highly valued, often because traditional industries are very heavy. In terms of market and operation, traffic is limited by channels and revenue is limited by sales, which makes it very important to rely on marketing talents to develop markets and sales. In terms of products and technology, the product cycle is long and the technology contains low gold content, so it is difficult to incite the market through products and technology. Therefore, in traditional industries, the most successful development is often marketing talents. Many bosses in traditional industries are from marketing or sales. Generally, they are top sales bosses, second-in-command planning bosses and bosses with little technical background.
