According to the British Broadcasting Corporation (BBC) reported that on the local time on June 24, the referendum vote for Britain to leave the Europe has been counted, the results show that 52% of Britain citizen support to exit from Europe, which means that the UK will be out of the EU. Influenced by the referendum, the pound plummeted substantially, the euro and the dollar also fell more than three percent, while the Swiss franc, the Japanese yen is skyrocketed, this brexit directly burns the global currency market, in order to stabilize their economic, and there many countries has been intervene the national economic.

European a major place for cross-border imports as electricity suppliers, and it is an important export market for cross-border electricity supplier. But now the state of the economy of the whole Europe is in shock period, the pound and the euro will likely to depreciate for a long period, which benefits domestic tungsten enterprises for importing related equipment. In this way, domestic tungsten manufacturers can improve the quality and quantity of tungsten products (tungsten heater). But on the other hand, export becomes an issue. Business profits will decrease. The industry said that at present the most cross-border electricity supplier for China and European logistics companies (excluding postal operators) in China have a layout in the UK, a large proportion of shipments should be pass the UK into the EU (dedicated line, overseas warehouses, etc.) . Therefore, for those service providers, they will be more or less affected.

In fact, the United Kingdom and Europe are not ready to the follow-up work for brexit. Britain has little effect to core business of SprintPack in a short time, because the British and European countries need to establish the appropriate bilateral agreements. The global economy will be in a long grace period, countries should make the appropriate measures to stabilize their economies.

Although the WiFi technology has become increasingly popular, but there are still exist some problems. If there are a lot of people connect a WiFi at a time, the internet speed will be very slow, and the wireless signal would become instability. What’s more, not all of places install the wireless network. For its own drawbacks of WiFi, German physicist Herald Haas and his team of the University of Edinburgh invented a patented technology that uses a bunch of flash to transmit the wireless of digital information. This technique commonly refers to visible light communication (VLC). In this way, LED bulbs can quickly transmit binary encoding. But to the naked eye, this type of flashing is not visible, only the light-sensitive receiver can detect it.

Visible light communication technology, the nickname of Li-Fi is not just improving the coverage of the Internet. As the most important technology of wireless data transfer, WiFi use radio frequency signals. However, radio wave is only a small part of the entire electromagnetic spectrum. With demand of users of wireless internet is increasing, the available radio spectrum are increasingly less. For example, when people surf the internet in a cafe, if there are more and more people use the internet, people will find that speed is very slow, which is the same as the 3G mobile networks. At the same time, according to Cisco's data, the amount of information transmitted through mobile devices is doubled every year. Data transfer rate of LiFi network is up to 1GBps, which is 100 times as quick as WiFi.

Once this technology can be improved perfectly, this will be a milestone for network information technology. The accelerating of the transmission speed of the network will help domestic enterprises, such as tungsten communicates with foreign enterprises. And it benefits domestic enterprises to get more foreign tungsten market information, which will bring good economic benefits to the world's tungsten market (tungsten heater).

Our country plays an important role in cemented carbide industry around the world, which is one of the main countries of raw materials and manufacture. Tungsten carbide materials have many advantages, such as high hardness, high strength, good thermal-setting, excellent wear and corrosion resistance and so on, which have been widely used in modern machining tools, wear-resistant materials, corrosion-resistant and high-temperature materials, etc, especially indispensable in tungsten carbide cutting tools. Development status and problems of cemented carbide industry in our country, mainly in three aspects: total production of large, relatively low profit margin; carbide products lack comprehensive export channels; related business technology innovation development is insufficient.

Although China in terms of production of cemented carbide is far ahead in the world, but at the margin is far lower than other developed countries. The main reason is that the domestic carbide products are mainly concentrated in the low-end products; the low degree of processing, low-tech, value-added products is not high, supporting the poor, such as the number of bars, plates and so on. While foreign enterprises focus on high-performance, high-precision and high-end CNC inserts, micro drills as well as some parts of precision instrument, so the profit is dramatically increasing. In terms of export channels, our carbide products export channels the vast majority still remain in the traditional way of wholesalers and retailers a simple intermediate channels. Each member of the channel as an independent economic entity, it will be in order to maximize their own profits, difficult to form a benefit-sharing, risk-sharing marketing model. Therefore, we should adopt multi-channel marketing management according to different carbide industries; design reasonable, flexible product pricing mechanism, keeping the right balance of sales channels; Improve information management of sales channels, improve the efficiency of distribution channels, establish direct marketing system, carbide production enterprises.

Xu Gao, one of the China Finance 40 Forum (CF40) -Youth Economist members, chief economist of Everbright Securities, indicating that the recent China's economy is in transition, many people do not understand the current economic situation. The understanding of China's economic situation from different observers from different perspectives will be quite different. Xu Gao thinks that the biggest risk of current Chinese economy is "utopian market." Over the past few decades, in order to achieve economic growth, China did many efforts in market reform. In this respect, China has made no small achievement, which made market-oriented direction become popular.

Some people think that market-oriented reforms should be accelerated, the sooner the better. They believe that the reason why the current chinese economy is now in such complex state is that the market-oriented reforms have not yet to a certain high level. These people hold the view that the market should be opened up and let the market adjust spontaneous for overcapacity, high debt and other structural problems of chinese economic. In this process, those overcapacity, high debt tungsten enterprises will be out of the market, leaving those more promising, more healthy tungsten enterprises.

Through such "cleaning", the chinese economy will be able to get rid of a heavy burden, leaving a strong team. Xu Gao considered this idea as "utopian market", which is too idealistic and not realistic considering the complexity. In fact, history proves that such a utopian policy cannot achieve the desired results, and even bring disaster to the economy of countries. If such thinking continues to develop and expand, it will only continue to interfere the development of the tungsten market (tungsten heater element), and it cannot keep the stable economic growth for a long-term. Therefore, China should be more pragmatic to promote a progressive reform idea.

The result for British voters elected to leave the European Union(EU) has been announced today, which will have far-reaching repercussions both domestically and internationally, and immediately plunged the 28-member political and economic union into its worst crisis since it was founded.

The vote result was at times bitter and acrimonious. The Leave campaign, headed by former London Mayor Boris Johnson, took 51.9% of the vote to the 48.1% that the Remain campaign, headed by Prime Minister David Cameron. According to British Broadcasting Corporation, 72% of the electorate voted.

The result had an immediate effect on the financial markets, with the pound plunging to a 30-year low against the US dollar and the Euro, Europe’s single currency, slid 3% against the US currency. The US has for years had British membership of the EU a core part of its European policy, while the UK and China are experiencing what Cameron and President Xi labeled “a golden era” after the Britain last Oct., when deals worth 40 billion sterling were announced. Now the referendum result to leave the EU is affecting the gold market greatly, which will lead the gold price to a increasing tendency apparently. It is said that gold, as a favorable hedge investment, will be more and more popular by the investors, which will push the gold price moving up.
