Evacuation doesn't means all people in landing area need to get away from the landing area, it's unreasonable since the population density is higher than you thought, instead CNSA using in-situ evacuation. Here I translate part of an evacuate guide in May 4th, 2018 full text 1. all the urban residents evacuate to nearby roads, parks, dams, fields 2. all primary and middle students evacuate to nearby roads, parks, dams 3. 4. 5. No vehicle allowed during evacuation, when arriving the evacuation point, keep watching the sky, keep away from high-volt tower, houses, construction area, the rest of landing area residents evacuate to the evacuation point appointed by the residents association. 6. all residents must follow the polices' and staffs' arrangement 7. residents should lock up and power off before leaving their houses 8. First air defense siren will be alarm at T-1h and evacuation begins, Second air defense siren will be alarm at T-0, Third air defense siren will be alarm when debris touch down and residents can return to their homes. Since they are all watching the sky, there is no doubt that they will take the footage when the debris dropping nearby 9 hours ago, kerbiloid said: Reveal hidden contents Reveal hidden contents Reveal hidden contents https://en.wikipedia.org/wiki/Dongfeng_(missile) Indeed, from nothing.

Nice. It's hypergolic, btw. Even the oxidizer decays in 1-2 days, while the fuel usually requires chemical neutralization.

Not only the technologies, the design language from USSR did effect China in many regions even today. Shenzhou and Tiangong are nice examples, they followed the same layout, just like nowadays almost all new manned spacecraft using two modules design now, but they are totally different in many aspects like size, functions etc. There is a comparison section in Wikipedia of Shenzhou. 2 hours ago, kerbiloid said: Nice.

Mostly they just drop on the mountain like what u see in the video, if they dropped on the houses, CNSA will clear the surroundings and compensate.

Such coincidence 50 years later and with no reasons to follow the old designs looks amusing. P.S. Won't be much surprised if the nextgen modular station will look like a simplified Mir.

It‘s a completely different design. The solar panels are attached to the cone on Soviet craft, on Wentian and Mengtian they have arms and attached to some metal frames. The metal frames have a smaller diameter, a cone-shaped adapter saves weight and provide some space for retracted solar panels, so they don't exceed the fairings during launch. Seems like this picture were wrongly translated. The socalled "unpressurised cargo module" is actually a 气闸舱(EVA hatch) ,and the control module is actually a 资源舱(Resource module), the hatch is on the bottom of the hatch module.
