how did china handle the pandemic?

They did not handle this pandemic situation they actually hide it from the world, This disease came from china how is it possible they have controlled it.

They barricades people inside their houses and guarded them with armed men and delivered food/supplies door to door.

They dealt with the problem early with their lockdowns. Everyone was already used to precautions like wearing masks. What's even more impressive is how quickly Vietnam and Taiwan responded to the events in China. 

They locked the country down and made everyone wear masks. They enforced the law too, so everyone complied and the disease was contained and eliminated quickly. There was no need for handouts because the Chinese do what they are told and they dealt with it quickly enough that they went back to normal. 

Unfortunately western countries do not have the discipline, so the disease continues to spread. 

By China being a strict kind of police state in the 1st place. The government controls/ monitors all aspects of life. So, when the government tells everyone to wear masks/ gloves/ stay home/ have a curfew...you do it or you get shot/ arrested/ lose all/ sent to a 'reeducation' (torture) camp. So, there is immediate and 100% compliance by the public.

And with Covid-19 since it has a 2 week cycle, with 100% total compliance and closed borders you beat the disease completely in a month, which is what happened.

Those 10,000's who suffered or died in a 30 day total lockdown are swept under the rug, not considered important in a communal society of 1.4 billion.

China C-19 ... 90,044 cases ... 4,636 deaths ... 85,225 recovered

China let the experts in the field of epidemiology chart the course. The Chinese people were united. As a result, infection rate very low and no extensive measures were needed. The US example what not to do (trump factor/people not united). 

China did not give any aid to the people, neither stimulus checks nor supplies. Sounds strange for a supposedly Communist country, eh?  Also there is no free health care; people have to pay the doctor before being treated.  

It did allow people to order food delivered, or to go out on an infrequent basis to buy supplies.  Everybody in China is required to have a cell phone registered with the government, and they often have a more private one as well.  I don't know how those without money got supplies - probably their relatives and connections helped in some cases anyway.  There were guards placed at each apartment building to make sure nobody went out more often than permitted.  

They all went into mask wearing right away.
