For the last two weeks, Eden Chen had been glued to her WeChat. A resident of the Chinese coastal city of Wenzhou, Chen and her family had been told to stay indoors, sending only one member out every other day to buy groceries. WeChat, the ubiquitous social media app in China, became an indispensable channel for checking up on relatives, exchanging information about quarantine measures and even getting on a waiting list to order now-scarce face masks.

China says it has launched an investigation into "issues" related to the death on Friday of a doctor whose early efforts to alert his colleagues to the dangers of a new coronavirus were quashed by authorities.

First came Liu Xiaohong's fever and a constant, throbbing ache. Then six days later, on Jan. 31 and with her fever still raging, Liu desperately rushed by bike to the nearest hospital; taxi services had been suspended days earlier as part of a citywide lockdown.

Doctors did a CT scan of Liu's lungs and concluded that day that she likely had the new coronavirus. Twelve days after falling ill, Liu is now waiting in a makeshift isolation ward for confirmation from a virus screening test so she can finally be admitted to a hospital.

More than a dozen cities in the Chinese province of Hubei are under official lockdown. And some cities and villages are taking it upon themselves to seal off their communities — even if their actions aren't legal.

It's all to prevent the spread of a new strain of coronavirus that has killed over 130 people and sickened more than 5,900 in China.

Wuhan's public health authorities say they are in a "state of war" as they quarantine the Chinese city in an attempt to halt the spread of a never-before-seen strain of coronavirus.

"Strictly implement emergency response requirements, enter into a state of war and implement wartime measures to resolutely curb the spread of this epidemic," urged a committee of Wuhan's top officials. "Homes must be segregated, neighbors must be watched."

It wasn't just the fact that one of China's best universities had changed its charter last December to emphasize loyalty to the ruling Communist Party that raised eyebrows. Shanghai's Fudan University also deleted principles like freedom of thought, and did so publicly, as if expecting praise.

Furious students staged a rare and risky protest in the school cafeteria in December. They sang the school's anthem, which praises academic freedom.

Taiwan's president, Tsai Ing-wen, has won a landslide victory in a hotly contested election, dealing a stinging rebuke to Beijing's efforts to control the island's democratic government.

"Democratic Taiwan and our democratically elected government will not concede to threats and intimidation," Tsai declared to thousands of cheering supporters at an election rally outside her party's campaign headquarters Saturday night. "The results of this election have made that answer crystal clear."

Millions of Taiwanese are preparing for key elections this weekend — and some are even flying back by plane to vote.

Taiwan does not allow absentee voting, so those abroad have to return to the exact county where they were born, or where they have a registered household, to cast their ballot.

China produces huge amounts of online data — and little of it is protected. That has led to a thriving market for stolen personal information, from national identification numbers to home addresses.

Some of it is used for state surveillance, while much of it is used for private extortion and fraud.

Hsu's Facebook profile was blank; it had just been created that morning.

At a recent election campaign event in Taiwan, a procession of women beat ceremonial drums, dance and wave lotus-shaped umbrellas in celebration. But beyond the slogans promising national security and prosperity, the topic on everyone's mind is what to do about China.

The star of the event is Han Kuo-yu, a pro-Beijing candidate running for president with the opposition Kuomintang, who poses a stark contrast with the current leaders.

President Trump has signed a bill signaling support for Hong Kong's protests, prompting Beijing to issue a sharp response and summon the U.S. ambassador to China.

The Hong Kong Human Rights and Democracy Act of 2019 allows the United States to level sanctions on individuals who carry out human rights violations in Hong Kong, which has been rocked by mass protests for more than five months.

Living quietly in Taiwan are several dozen young Hong Kong protesters who, one night in July, vandalized Hong Kong's legislature during ongoing anti-government protests.

Their arrival in Taiwan has revived a fierce debate on the small, self-ruled island over whether it can — or should — accept Chinese citizens seeking safety.
