Answer: 1. It means that at the time of trademark registration, due to various reasons, the products with this trademark have not been widely recognized by the society. However, with the efforts of enterprises, the products using this trademark are slowly gaining popularity. Slowness has been widely recognized in society, which means that a brand effect has been produced, which means that the distinctiveness of the trademark has grown from scratch. For example, Haier Electrical Appliances, which was not well-known before but has now become a famous brand, falls into this category.

2. The progression of the distinctiveness of a trademark from existence to non-existence is the opposite of the above. It means that this product has been widely recognized in society and is a high-quality product that is trustworthy by consumers. However, in the later period, due to various reasons, the quality of the product or service declined or there were some problems, resulting in a decrease in public recognition. This is commonly known as "the brand stinks". This is when the distinctiveness of the trademark disappears.
