I totally disagree.
I have been visiting China since 1998, going there every year as a foreign expert. This ended when Covid came. But we made another visit last year in September because I wanted to see my friends and colleagues and also see what China was like now. Nothing was more simple. We did not need a visa and even though the entry card required the name of the hotel nobody ever asked for it or seemed to care. We just simply walking and could do whatever we liked. This doesn’t mean the government doesn’t have an eye you. Of course there is registration at the hotel but also every train ticket is connected to your passport. So you are watched every second of the day, but it did not bother me, I have nothing to hide. And I realise that WeChat probably also shares every ice cream and cup of coffee you spend with the Party.
We were in Shanghai for a few days and found it a very pleasant, friendly and clean city. When the light turns green at the intersection the hoard of motorbikes takes off without a sound. Most vehicles are electric, nothing like the noisy and smelly tuk-tuks and wannabe racers of Bangkok. Hotels are affordable, as are restaurants.
Travelling is very easy. There are very many train connections, they are reliable, run on time and not really expensive. Obtaining a ticket can be online or at a ticket office, always have your passport present.
For Internet we bought a SIM card at True, in a shop you can find in many of the malls. It worked very well with sufficient data. In most public places there is Wi-Fi. Use of a VPN maybe necessary, depending how you use Internet. I use GooseVPN, a reliable service with an excellent helpdesk.
For payment everybody uses WeChat. You can either have a QR code scanned on your phone or scan a code yourself. Even the bicycle taxi showed me the QR, and although I have brought some cash money I didn’t use a single renminbi. You can connect your Wise card or any other card with WeChat. For me it worked well, my wife’s MasterCard was blocked after returning, for abuse detected by the issuer. So you do need to keep track of your spending carefully and set your limits right.
China has a lot to offer in terms of nature and history. It is an interesting country and under the present circumstances we will certainly go back there.
