Planning a visit to the UK? Here we help with ways to cut your costs. 

AVOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival （19 Oct. ） cost £ 169. 15 at Booking. com. A week later, the same room cost £ 118. 15.

If you can be flexible and want to know dates to avoid or you're looking for a big event to pass your time-check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category. 

STAYAWAY FROM THE STATION If traveling to your destination by train, you -may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday. 

Don't be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge's Central Euston hotel in London for Saturday 22 September was £ 95. 95. A room just a tube journey away at its Covent Garden hotel was £ 75. 75. And at Farringdon, a double room cost just £ 62. 95.

LOOK AFTER YOURSELF Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of city centre buildings. A great example is the historic O'Neill Flat on Edinburgh's Royal Mile, available for £ 420 for five days in late September, with room for four adults. 

GET ON A BIKE London's "Boris bikes' have attracted the most attention, but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you. on public transport or car parking costs. 

Among the smaller cities with their own programmes are Newcastle （casual members pay around £ 1. 50 for two hours） and Cardiff （free for up to 30 minutes, or £ 5 per day）. 

Liu Yexi has taken Douyin by storm. As of Nov 17, the virtual idol, who debuted (首次出现) on the social media platform on Oct 31, had only released two short videos but attracted over 5 million followers.

Different from other virtual idols, Liu is defined as a “virtual beauty vlogger”. In her first video, Liu is doing makeup with an eye brush while dressed in a traditional Chinese costume. When she turns around, the onlookers are terrified, except one boy. Then Liu slightly brushes the boy's eyes, allowing him to see the fantasy world in her own eyes.

The internet users marveled at its storyline, science-fiction elements and special visual effects with cyberpunk style. Liang Zikang, the CEO of the production team, told China Newsweek that the team spent two months making the video.

Liu's instant popularity online further reflects that the virtual idol industry in China has  been booming. There are over 32,400 virtual idols that have opened accounts on video-sharing platform Bilibili in the past year, seeing a year-on-year rise of 40 percent, Chen Rui, the CEO of Bilibili, said in a speech.

“Compared with real idols and stars, the virtual ones seem to be more approachable for fans,” Shine News noted. Additionally, these virtual web celebrities won't have scandals.

As more young people are fascinated by these virtual figures, their commercial value has been on the rise. Generally, they earn money by endorsements, online concerts, livestreaming and related products.

Therefore, some people are wondering whether they will replace real humans. “These so-called virtual idols have real human teams to back them up and control them. They are not really virtual,” Ding Daoshi, an independent analyst in the internet sector, told the Global Times. The real virtual idol will come when artificial intelligence achieves a new level of self-learning and self-training and then interacts with others, he added.
