Wolf WarriorⅡ(《战狼2》), a movie that made box office history in China, tells the story of how the Chinese government successfully rescues (营救) overseas Chinese citizens in Africa.

At the end of the film, there is one line that stands out: “When you encounter (遇到) danger in a foreign land, do not give up! Please remember, at your back stands a strong motherland.

The movie sends the message that overseas Chinese will always receive timely help from China. But in the future, some headstrong(任性的) citizens will not get this help for free, People’s Daily reported.

On March 26, 2018, the Ministry of Foreign Affairs (MFA) worked out a draft for regulations (条例) on consular protection and assistance (领事保护与协助), the Xinhua News Agency reported. The draft says that those who choose to travel to dangerous places without considering warnings by the ministry will not be able to take advantage of free rescue services.

For example, the ministry recently released a travel advisory (警告) saying that Chinese citizens should avoid traveling to Maldives. Chinese who travel there and run into trouble may still ask for help from the Chinese Embassy (大使馆). But they will have to cover the cost of their rescue later.

In fact, this is a common international practice, People’s Daily said. Countries like the US, the UK and Canada have similar regulations.

Masick Czastka was born in Lodz, Poland. He came to China several years ago. So far, he has been working in Chengdu for three years. “The Belt and Road Initiative(一带一路的倡议) is meaningful”, he said. “Thanks to it, we have more chances.” The most powerful support for Chengdu to thrive(繁荣) along the Belt and Road is the Chengdu Europe express railway. It provides direct train services between Chengdu and the city of Lodz.

Because of the express railway, trains can bring things from China to Europe. At the same time, they can bring back European food, wine, meat and so on. In 2017, a total of 1,000 trains ran between Chengdu and Europe.

Since the Chengdu Lodz express railway was opened. Chengdu together with other cities in west China, has developed close trade ties with the European country. Poland is one of the largest apple producers in Europe. Czastka’s company helps farmers in Poland sell their apples to China. More and more European products will be sent to China in the future.

In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead, with more tactics(策略).

One tactic involves where to display the goods. For example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food later in their trip. In department stores, the women’s shoe section is generally next to the women’s cosmetics(化妆品) section: while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over and find some cosmetics they might want to try later.

Besides, businesses seek to appeal to customers’ senses. Stores notice that the smell of baked goods encourages shopping, so they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wines went up.

When it comes to the selling of houses, businesses also used highly rewarding tactics. They find that customers make decisions in the first few seconds upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the pool through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.
