11. When it comes to advertisements for famous products, the first thing that comes to mind is the OPPO mobile phone ad. I think I often saw this ad when I was in high school. Back then, it was everywhere—mainly on buses, bus stop billboards, and sometimes on TV too. From what I remember, I must have seen this ad four or five times a day, so it left a really deep impression on me. The product in the ad was an OPPO phone; I can't remember the exact model anymore, but I do recall one of its features: "Charge for 5 minutes, talk for 2 hours." I remember quite liking this ad at the time because we thought the way it was advertised was funny and interesting. It used an exaggerated comparison to show off the product's advantages. My classmates and I even used to joke about this ad, like saying "I'm so undisciplined—5 minutes of homework, 2 hours of gaming." Because this ad really brought us a lot of joy back then. Overall, I think this was a very successful ad because it directly showcased the phone's biggest feature. Moreover, it was simple and straightforward, highlighting the durability of the phone's battery by contrasting the short charging time with the long usage time.
2. When it comes to second-hand item platforms, the first thing that comes to mind is a platform called Xianyu. It's a recently developed second-hand trading platform where anyone can freely buy and sell second-hand products. I know about this platform mainly because it has done a lot of promotion, placing a large number of ads on various social platforms. So I learned that if you have old mobile phones or unwanted items, you can sell them on this platform. Also, some of my friends use this platform sometimes, so they recommend it to me. For example, they put their expensive, relatively new but unwanted clothes or bags on this platform and can get a good income, then use that money to buy what they want. They sometimes even exchange their second-hand products with each other on this platform, such as some decorations or even furniture. As for what you can buy, this platform is actually quite versatile. At first, I thought it only sold second-hand products like furniture, some plants, or clothes and bags, but I didn't expect that sometimes it even sells second-hand movie tickets—meaning some people buy tickets but then can't go due to changed plans, so they sell the tickets at a low price. All these surprised me, and I actually quite like this platform. Because on the one hand, I think it reduces a lot of unnecessary waste. Many second-hand items are still in good working condition or appearance; if they are directly discarded in such cases, it causes unnecessary waste, which is not environmentally friendly. But such second-hand platforms successfully recycle them. On the other hand, I think it provides people with high-quality and affordable things. Because second-hand items are usually cheaper, so people can get what they want with less money, which is very useful for students like me who don't have much income.
