Many youngsters in China enjoy gathering a couple of good friends and taking a relaxing walk through the streets, which is a popular form of visiting a new city, that is, Citywalk. They can follow a special urban route (路线), exploring old building, drinking a cup of coffee, or eating local snacks. It can be a special guided trip for a small group of people, or simply a relaxing walk for one or two to explore new areas, sticking to the key point: avoiding famous tourist attractions and big crowds to get a more interesting experience of the places you visit.

In China, the Citywalk trend (趋势) is spreading from big cities like Beijing and Shanghai to other cities, encouraging more people to take part. Xiao Yiyi is a young visitor from Changsha exploring new possibilities while traveling. Recently she tried six Citywalk routes to walk in different cities and posted them on her social media account, with the aim of sharing experiences to “walk in open-air museums”.

Citywalk not only offers a way for young people to interact with a city but also provides an opportunity for people who share the same interests and ideas to easily make friends. Xiao Yiyi said her group usually includes a few or so people and her trips last around half a day.

Even though Citywalk is a new trend, industry insiders say that its future possibility is huge. It is offering a beneficial change to travelers as they can better choose the experiences that suit their interests and needs. At the same time, Citywalk gives an opportunity for tour guides and travel service providers to offer a more professional service to meet ever-changing market needs.

They already guide blind and disabled people; now dogs are to be trained to help people with dementia (痴呆) or Alzheimer’s. Alzheimer’s can make people confuse night and day or forget basic things such as washing or drinking enough water.

The dogs will be trained to respond to sound triggers (触发器) in the home that cause them to perform tasks. The duties will include reminding their owners to take medicine, as well as encouraging them to eat, drink and sleep regularly.

The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer’s Scotland and Dogs for the Disabled. The first dogs will be distributed to four Scottish couples, where one of the partners is in the early stages of dementia. Some 670,000 people in Britain have dementia and one in three over 65 will develop the condition. By 2021 this is expected to rise to one million.

Joyce Gray of Alzheime’s Scotland said, “People in the early stages of dementia are still able to live a relatively normal life, and dogs help to maintain routine.” Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship. Ms Gray said, “The evidence is that people may forget familiar faces but not pets. It’s such a strong bond that people often remember them longest. People don’t need to communicate verbally (言语地) but they can still interact. You can have a speechless bond.

Helen McCain, director of Dogs for the Disabled, said, “People with dementia often forget to take the medicine. If a dog presents them with a bag with pills in it there’s a greater chance of them taking it. The dog would also encourage the owner to take them out for walks, ensuring they keep exercising and interacting with other people.”

Have you ever noticed that after about 6 months your perfectly new 1，000 dollar smartphone begins to slow down? What if I told you that it’s a sales strategy that pretty much all phone companies use to force people into buying new phones?

In late 2015，when Lisa Young was in charge of iOS security and beta software testing teams，her boss revealed a dark secret to her，saying that they were using a new strategy that would purposely slow down older phones every time the phone would upgrade to the latest opera ting system. This new method would force customers to buy the latest phone model，increasing sales by 70％.

She was a little disturbed to hear the news，but she just kept her head down and continued to do her job. After a while，the guilt of being involved with such a shady sales model started to weigh heavy on her. “How could a multi—billion dollar corporation continue to take advantage of the public like this?” she thought. In March of 2017，she contacted a reporter from CNN to finally leak the information concerning Apple slowing down phones.

The scandal(丑闻)went viral overnight，and every media outlet in the world，in every language was talking about it，making it one of the biggest controversies in consumer electronics history. A week later，she was secretly let go after her 8 years of service. Although she was taking a huge risk going against one of the most powerful corporations in the world，she felt a sense of relief exposing them. The public deserved to know and the fear became her motivation to find a way to destroy their shady sales model.

Several of her colleagues were fired with her. They quietly united，and after a year of extensive research they designed a unique product called Circa Charge that would reverse the negative effects of “software updates.” Phone companies have recently caught wind of their overnight success with CircaCharge and are trying to do everything they can to make this product illegal and ban it forever. Lisa and her team have ma de unbelievable progress in increasing battery life，battery health，and optimizing phone performance，and they will continue to develop new technology that will beat phone companies at their own game until they change their ways.
