The building is called the Regent International and is located in Qianjiang Century City, in Hangzhou’s central business district. The structure is one of the largest in China, standing at 675 feet tall, and covering 260,000 square meters. The building can house up to 30,000 people and is currently believed to have 20,000 tenants. People are allowed to leave the building, of course, but they certainly don’t have to. The Regent International contains barber shops, nail salons, supermarkets, swimming pools, cafes, and a food court, making venturing outside completely unnecessary.

Unsurprisingly, Regent International was originally designed to be a hotel. The designer, Alicia Loo, had already contributed to the Singapore Sands Hotel, which is the world’s second seven-star hotel, and wanted Regent International to be a six-star hotel. However, the purpose has now changed and the building currently contains apartments rather than hotel rooms. Monthly rent at Regent International will set you back 1,500 RMB per month, which equates to roughly 211.16 USD. If you opt for a unit with a balcony, that’ll cost you 4,000 RMB per month, which is estimated to be equivalent to 563.10 USD.

Not too bad, not too bad at all!

Technology is all over the place these days, and the people who are supposed to buy it are struggling to keep up both financially and mentally. Alongside some inventions like drones, AI, and facial recognition that seem straight out of the future has come a whole army of bizarre little machines that aren’t practical, aren’t made well, and frankly, no one ever asked for. And what do they all have in common? For one thing, they were all developed, funded, and managed in the startup hub — AKA a cesspool of money and dreams (and dreams of money) called Silicon Valley. Here are the weirdest inventions of the last decade you want to make sure you didn’t miss.

For just $199, you can have a brush that listens to your hair and tells you when you’re brushing too hard or in the wrong direction – or at least, you could have.

But after this idea majorly flopped, L’Oréal not only stopped producing them…they also tried to wipe as much evidence off the internet as they could that the weirdest of their inventions ever existed.

It’s no secret that younger bodies have blood with more healthy properties, or that it’s just a part of the natural aging process…one that not many people want to risk messing with (including doctors). But Ambrosia saw a business opportunity here, one in which the precious rich blood of younger people could be bottled up and sold – for thousands of dollars per liter, mind you – in order to change the way we age. The idea was based on a very small and unpublished clinical trial run by a Stanford medical grad (not a licensed doctor) who found that fresh blood helped Alzheimer’s patients. But the FDA didn’t seem to think the evidence held up and shut down the company.

Though microchips aren’t new — they’re usually for dogs, children, and perhaps anyone else who can’t be responsible for themselves. But in 2015, more than 300 startups hired a Swedish incubator called Epicenter to microchip their employees in order to allow them unconditional “printer access, key-free entrances, and wireless payments.”

This is actually ongoing, so it might be smart to check with any prospective companies before signing a contract if you don’t fancy a new piece of metal in your flesh.

Neutrogena’s Light Therapy Acne Mask was released in 2016 – without the ample warnings, it actually needed. Its red and blue lights are meant to have some anti-inflammatory properties, but in the end, it turned out they could also blind you.

After many eye conditions came up as a result, the product was recalled.

Washing machines that require quarters are a nightmare; there can be no laundry done without ample planning and saving of the little metal coins, which – until recently – were also in high demand for parking spaces and the like. But in 2014, a company called Washboard set out to change all that – exchanging your credit payment for quarters (with just about $7 of interest shaved off). Despite a few devoted customers, the founder himself said that he struggled to convince people that the company was even real… which, today, it no longer is.
