I selected software are railway 12306, Tencent QQ and Alipay
12306 Railroad
12306 railway is China Railway official produced mobile ticketing client, convenient and quick, I was introduced by others learned of this software, and then downloaded to be their own users. Their main service is a type of software, in order to facilitate the travel of customers, it is of course there are some Bug, you can download the latest version of the installation package can be installed. The software officially launched trial operation on December 8, 2013. It is saying about the same software, such as Ctrip, Chi Heng they basically have to grab votes functionality, and 12306 less have this feature. In my opinion, although the 12306 tickets the official website, but the development of other ticketing software is booming. This software is also very easy to use, just select the starting place and time to find their favorite ticket, timely and accurate data, transaction secure. I first used this software is a sophomore, Liu Qiang teacher is a teacher, was in Hefei, according to introduce their friends to download. Familiar with the software no difficulty, as well as their own exploration by introducing others soon find out. The benefits it has brought me a ticket is convenient, is still with me now, because it is very easy to use and because it is the official ticketing website. After personally I think he will still exist, but will become more intelligent, because he facilitated people's lives, saving everyone time.
Tencent QQ
Tencent QQ is a dating chat software, the reason for that is because it was once very fire, the goal is profit, it is a lot of cooperation with telecom operators to provide wireless communications value-added services to achieve profitability. I was by downloading to your phone.
The software also exists the Bug, you can download an updated installation package can be installed. The software and released in February 1999, the same type of software generally will come to participate in the competition by more ornate page, but they are still not as good as the development of this software. Using this software, I feel it is very frequent update frequency, smarter, more convenient. The first time the use of this software is the sixth grade, Zhang Xing teacher is a teacher, in the home, by downloading the registration. Proficient in the software is not difficult, practice makes perfect, it benefits me it is very easy to contact others, multi-user chat when you can establish a direct discussion groups, send files is relatively easy. I'm still using it, in addition to the software, I also use micro letter, but not as good to use QQ, send the file is not very convenient, and if you delete pages and chat with others, will be removed at the same time chat between you recording. I still think it will still exist after, because of ease of use.
Alipay
The reason for using Alipay online shopping may or because of it, it is a profitable software, its profit model has several convenient services such as commissions: the current third party payment companies and banks sign the agreement first, to determine the commission rate paid by banks ; then, the third-party payment platform based on this rate, coupled with its gross margin as a service commission, charged customers; there is advertising revenue. Alipay posted on the home page targeted advertising, including banner ads, button ads, interstitial advertisements. Overall, less space occupied by the ad layout, layout design is reasonable, reflect the content simple, strong visibility features. But also on the home page as well as a number of public service ads, allowing users to learn more about the information technology industry. There are other financial value-added services, such as to buy the plane ticket, send gifts on behalf of other living services. The software is downloaded through their use.
Alipay also there are some Bug, you can download the latest version of the installation package can be installed. Alipay company established in 2004, the second quarter of 2014 began to become the world's largest mobile payment companies, with Alipay similar software such as Paypal, TenPay, mainly 100 Po and the payment of APP banks, etc., banks and Alipay competition through subsidies and emit a lot of preferential policies, but still not as good as Alipay development of good, but that is state-owned enterprises, the development is fairly impressive. Many Alipay inside the small program, very convenient, everything. The first time I use Alipay when sophomore, Liu Qiang teacher is a teacher, in the home, through their own download. This is also proficient or practice makes perfect, the benefits of this software is easy to use, do not go out with cash, and taking a lot of handy software. I still use this software because of its high safety factor, it is also very convenient. This software will still exist in the future, their high safety factor, the majority of users, there is still very convenient.
