The only reason you can leave your city here is to provide help to someone else. For example I left my city twice to visit my grandparents and deliver them some goods. You should always send a text to a government number first informing them about it though or you can just write down on a paper where and why you are going.
I obviously prefer writing these info than texting and I haven't faced any problem with the police till now!
the whole situation is quite shitty, i hope the lockdown will end soon!
Hope so too!
Take care yo!
