Now movie creations are reusing the popular subject matter to re-use a subject matter. There is a market, and many people are rushing up. This is not a healthy movie ecology. In contrast, the mining of national culture is rare, such as the traditional festival Dragon Boat Festival. The development of the background such as the Mid-Autumn Festival and the use of ethnic art elements such as Kunqu opera and Huangmei opera are rare. Once you deliberately explore this cultural wealth of the Chinese nation, you will be presented with a wonderful treasure trove of art in front of the creators. There will also be a spring full of flowers. What is the most accurate summary of the subject matter of this text? ['Domestic movies need to work hard to get rid of unhealthy ecology.', 'Domestic movies will usher in spring of flowers.', "Domestic movies can't fall into the misunderstanding of theme reuse.", 'Domestic films should dig deep into the treasures of national culture.']
