5-year-old Zhang Wang trains to walk on wires in a series of ‘Spartan’ workout plans designed by his father. The plans include one-arm push-ups, rock climbing and Chinese Kung Fu cudgel.

The boy from southwest China’s Sichuan Province has become an internet celebrity in China.

His father, previously a migrant worker, has his son’s best interests in mind, despite the training seeming quite arduous for such a young child. The father hopes that training his son like this will build his confidence and extend his range of interests.

His father sees safety as a top priority and always accompanies his son when training.

More and more Chinese people have followed the fashion of giving out digital “red envelopes,” cash gifts exchanged through a smartphone app, to friends and relatives while celebrating the Spring Festival, also known as Chinese lunar New Year.

A survey conducted by United Overseas Bank (UOB) showed that three quarters of Chinese people plan to give out their “red envelopes” through their smartphones during the Spring Festival holidays, China Youth Daily reported.

And the reason for the increasing popularity of the digital “red envelope” over the traditional ones is because of the freshness, fun and convenience it brings, the survey shows.

Lately, updates to Tencent’s QQ and Alipay, two popular apps in China, have added to the fun people can experience while giving out and grabbing the digital “red envelope.” With the introduction of Augmented Reality (AR) technology, grabbing the digital “red envelope” through these two apps will be similar to playing the game Pokemon Go.

In the meantime, another survey by Rong360, an online financing platform, has shown some worrying results. It said nearly 21 percent of the people surveyed said they used to be at odds with their friends or relatives because of digital “red envelopes.” Nearly 20 percent of the people surveyed said that the atmosphere of New Year celebrations was affected with family members busily grabbing “red envelopes” through the phones.

The Rong360 survey also showed that 46 percent of those surveyed said they had given out “red envelopes” just to get people to praise or forward their postings on social media like WeChat or Weibo. But over 29 percent of people said that they will just ignore these digital “red envelopes”.

The giving of red envelopes on occasions like Chinese New Year is a tradition among the Chinese people. Typically, older members of the family give the red envelopes to the children in the family to celebrate lunar New Year.

Hebei will link weather forecasts with health risks, a move to inform people who are sensitive to changes in the weather so that they can take precautionary measures, authorities said.

“We are doing research into the influence of meteorological conditions on diseases and are setting up a database of information on diseases that can be more easily caused due to weather changes,” said Zhang Zhongjie, head of a service center at Hebei Provincial Meteorological Bureau.

The index will list the possibility of weather conditions causing various illnesses such as respiratory diseases or skin allergies.

They will be generated based on big data from local environmental and meteorological conditions, and recent patterns in diseases, Zhang said.

According to Zhang, Hebei has been studying the influence of air pollution on public health since last year.

“People are starting to pay attention to the weather and air, because air pollution in recent years has greatly affected their lives,” he added.

Ding Xiao, a young mother in Shijiazhuang who has a 10-month-old son, complained about this winter’s weather and smoggy air conditions.

“I have become a frequent visitor to hospitals because my son always catches a cold or gets a bad cough when the weather is bad,” Ding said, adding that many mothers are like her.

People in the province, which has been severely hit by air pollution in recent years, have complained about local weather.

“After all, it is their health that people are worrying about, rather than just the environment,” said Gao Yu, a doctor at the Children’s Hospital of Hebei province.

Gao said it’s necessary and useful to inform people of the specific weather index in advance.

“People need to know when bad weather is coming and how bad it is, just as they need the air quality index, through which people can know if the air outside is good or not and can decide accordingly whether to do outside activities or whether to wear face masks,” Gao said.
