I&;m glad to answer this question. There is no need for isolation. You need to scan Suikang Code when entering and leaving communities and public places. Suikang Code has a two-dimensional code in every community and public place. After scanning the code, the system will give you a health code according to your action track and big data evaluation, and you can freely enter and exit by leveling this health code. I hope the answer can help you, thank you! {! — PGC_VID:{&”;thumb_h: 512, &”;vpost: &”;-sign.toutiaoimg.com/tos-cn-i-0022/be72925d52024d8596970a73f406cd0d~noop.imag: 288, &”;vid&”;: &”;v02016e20000bqlmmr4pg62eavs6brc0&”;, &”;vu&”;: &”;v02016e20000bqlmmr4pg62eavs6brc0&”;, &”;duration&”;: 36.672, &”;thumb_url&”;: &”;tos-cn-i-0022/be72925d52024d8596970a73f406cd0d&”;, &”;thumb_uri&”;: &”;tos-cn-i-0022/be72925d52024d8596970a73f406cd0d&”;, &”;vid: {&”;high&”;: {&”;duration&”;: 36.672, &”;h&”;: 512, &”;w&”;: 288}, &”;ultra&”;: {&”;duration&”;: 36.672, &”;h&”;: 512, &”;w&”;: 288}, &”;normal&”;: {&”;duration&”;: 36.672, &”;h&”;: 512, &”;w&”;: 288}}} –}
