The writing techniques at the beginning of a composition are as follows:

1. Introduce the topic: First, you can attract the reader's attention by introducing the topic. For example, you can elicit your thoughts based on current social hot spots, issues that people are generally concerned about, or your personal experience. This will make the reader interested in your idea and want to know more.

2. Set a situation: In order to better present your ideas, you can set a specific situation to make it easier for readers to understand and react. For example, you can describe an event you have personally experienced or a phenomenon you have observed, and then present your thoughts based on that.

3. Ask a question: By asking a question to trigger readers' thinking, you can make them curious about your ideas. For example, you could ask a question related to your idea and then describe how your idea answers the question.

4. Quote a famous quote or story: Quoting a famous quote or a story as the beginning can increase the depth and persuasiveness of the composition. You can choose a sentence related to your idea or a story that supports your idea, and use this as an introduction to guide readers into your thinking world.

5. Describe the scene: Draw the reader's attention by describing a vivid scene, making them feel as if they are immersed in it. You can choose a scene that is relevant to your idea, and then let the reader feel the atmosphere and emotion of the scene through detailed description and emotional rendering.
