The jewelry and jades of the common people had gone through many changes from ancient times to modern times. In ancient times, jewelry and jade were mostly exclusive to imperial families and nobles. Commoners rarely owned them. For example, many dynasties did not allow commoners to wear jade, and the wearer had to choose the corresponding grade of jade according to their status. With the development of the country, the prosperity of society, the improvement of mining technology, the excavation of ancient tombs, and the exhibition in the museum, jewelry and jade gradually became gifts for engagement, marriage, and childbirth. It also became the object of pursuit and collection by players. The price even soared under the influence of the capital market and external factors. Nowadays, jewelry and jade seemed to have "fallen among the people" and entered the homes of ordinary people. This was due to the development of the Internet. Many merchants poured into the Internet, making it cheaper and more affordable to buy jewelry and jade online than offline. However, there were also many problems in the online market, such as the flood of fake and inferior goods, the fact that fakes sold better than the real thing, and the low popularity of the real live broadcast room. For non-experts, buying it was more risky. At the same time, there were also problems with the reputation of the merchants during the purchase process. For example, in the live broadcast room of the fast-handed "People's Jewelry", there were cases where the payment was not delivered for seven days, the customer service did not handle it properly, and it was involved in fraud. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

They could write about their childhood memories, interesting things in school, or their experiences in society. For example, Han Han could write about his racing experiences. In his novel, he could also incorporate stories from a certain field that he was familiar with. For example, if he was good at music, he could write about the encounters of a young man who pursued his dream of music in the music industry. 3. ** Has a certain degree of social criticism ** - To criticize some social phenomena indirectly or directly. This could be thinking about the education system, social values, or interpersonal relationships. For example, it described the unfair treatment that young people faced in society, or exposed some vanity and hypocritical social phenomena, and expressed their attitudes through the dialogue of the characters or the development of the plot. ** 3. Character Creation ** 1. ** The young protagonist of the town ** - Setting up a protagonist with a small town background, he might bring the simplicity and simplicity of the town, but at the same time, he might have a yearning and uneasiness for the outside world. Such protagonists often had unique characteristics, such as stubbornness and persistence. When faced with the prosperity and complexity of the big city, a series of stories would happen. His values might be impacted, but he might also stick to his original heart. 2. ** Car-related elements (if appropriate)** - Due to Han Han's close relationship with racing, some car-related elements could be added to the novel. It didn't have to be a race car. It could also be a worn-out car that became an important partner in the protagonist's life. It could symbolize freedom, dreams, or a tool for the protagonist to escape from reality. The car could appear in some key plots, such as the protagonist driving to find his dream place, or some conversations that had a major impact on his life in the car. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
