The MoBike official cost is about 3000 RMB(used to be 6000 at first). But there is some additional cost: the parts are not standard, and the design is totally new. When they produce more the cost will come down. I don't think such a bike worth 3000, but maybe true, they can be much cheaper to achieve better experience though. Shared bikes should bear any weather or rude users, this also increased the cost. And generally, your own bike is not supposed to be in rain storm very often..

I think it's just because these bikes are very cheap, maybe the guard system is the major cost. Indeed, some of my friend's bikes were stolen even carefully locked(about 1500-3000 RMB). On the contrary, mobike use steel frame not Aluminium(so it's heavy), doesn't have a derailleur, and other parts are all very cheap. Which make it's cost to be very low(I can buy such a bike with 300 rmb). So just buy one will be more convenient. p.s I live in Wuhan.

There is block based on content now, but not by check package by gov themselves(is it possible?). Search engine in China must follow the instructions by gov to block some content, which is the reason that google exit China. What I've learned told me if you have encrypted, it's impossible to get what you sent without a key. If it's possible, clearly it's in use in CIA too, not just GFW.

I don't know how GFW work exactly, but I think it's not blocking based on content, which means to check every page. What China gov want to do is just prevent those naive people from being deceived by some vicious foreigners, and they don't really care about normal college students or programmers(we don't care about politics too). Indeed, en.wikipedia is unblocked at all, and we can get all academic resource(including history, most universities bought them). So if you know English, you can get everything about, e.g., 64 event. Even the gov is more anxious about contemporary politics, clever guys can get some information by just refer a politician as "big tiger".

So, 1. Chinese gov don't care about those who just want to paste a photo on twitter, they blocked website such as twitter because it's known by even some Chinese farmers or workers. They are supposed to be susceptible, which means, danger.

2. It is said that China will block by whitelist instead of blacklist(maybe like North Korea), but they didn't do that.

3. Usually, someone who can buy and setup a server for himself is clever enough to distinguish between lie by terrorists and the truth.

Nearly all vpn that you can get now by searching will be blocked when they are becoming popular quickly. But if you have your own server(or a vps) and setup a vpn or shadowsocks server, there will never be such problem. It's because China block website via blacklist, so only some well-known ip will be blocked. Many friends of mine is using shadowsocks to unblock now(I'm a Chinese :).
