After “sleeping” for more than 3, 000 years, the Sanxingdui Ruins site (三星堆遗址) surprised the world. Hundreds of cultural relics (文物) have been found there. Here are some relics who want to say hello!

The large bronze mask (青铜面具)	I look strange, but I am not an alien! I was dug out from the second pit (坑). Some scientists think I am made like Cancong, the first king of Shu, and others think I have close relation to Zhulong, the Torch Dragon (烛龙).
The unfinished gold mask	Although I’m unfinished, I’m still in style. People who found me told me I am expensive because I am made from 300g of gold. They said my look shows that people of Shu worshiped (崇拜) gold.
The bronze standing figure (人像)	I wear a tall hat and a long coat with dragon patterns. I am the world’s oldest life-sized standing human figure. Many people think I might be an image (塑像) of the king of the ancient kingdom (王国) of Shu.
Some bronze vessels	We are bronze cups for holding water or wine (酒). We are also in dragon patterns. Some of us are square, which means we were only used by the king.

①Do you know podcasts (播客)? Have you ever paid for educational podcasts or live videos? Ask some people and most of them will say yes. “Pay-for-knowledge” has been a fashionable thing these years. Everything you think of can be found online, skills of talking, designing, computer programming and so on.

②Why is “Pay-for-knowledge” industry (产业) developing so quickly? First, its development is based on (基于) the Internet. With a fast network and a smart phone, anyone who has passed the identity (身份) check can be an online teacher, and anyone with an online account (账户) can buy “Pay-for-knowledge” products that he or she wants at a good price. Second, people are afraid to miss any information. They hope for more useful information which is usually at the hands of experts. Moreover, the need to learn new skills in today’s job market also pushes people to learn on such educational podcasts.

③The industry of “Pay-for-knowledge” has proved to be a great way of making money. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What’s more, this is a reflection (反映) of people’s respect for knowledge and talents.

④However, “Pay-for-knowledge” also causes a few problems. For one thing, the market is full of eye-catching words such as “How to be a good CEO?” which sound like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. That means, with or without these products, they can make it anyway, because they are those who have the ability to learn by themselves.

⑤In general, the best is the one that suits you most. “Pay-for-knowledge” may be used as a good start for self-growth. But be careful when you make a choice, or your dream of success may not come true.
