What is a DIY enthusiast? Why DIY? What is it short for? I'm a novice. I just checked the meaning of "rookie" the other day.

English abbreviation for "Do it yourself". Rise in recent years, and gradually become a popular. Simply put, diy is to do it yourself, regardless of gender and age. Everyone can do it by themselves, and the diy products have their own freedom and comfort. Diy originated in Europe and America and has a history of more than 50 years. In European and American countries, because the wages of workers are very high, you should try not to find workers for maintenance or furniture and layout at home if you can do it yourself, which can save wages. Foreign diy products companies usually have a series of supporting materials, such as materials and tools. In addition, the instructions attached to the product are very detailed, so there will be no difficulty in the process of doing it yourself, and the accessories of diy products are also easy to buy in supermarkets. So diy products, like ordinary goods, can be bought everywhere. In English, the verb followed by -er generally refers to people engaged in the industry, so diyer refers to people engaged in the above-mentioned industries.
