15 years (almost to the day) after I first landed in China, I was back, once again in Shanghai. I didn't have a lot of free time since I was there for work but I did manage to visit and explore a few places and thing back on what has changed and what has not changed.
And much has not changed. Physically much of the original and older Shanghai still remains as it was, with fairly narrow winding lanes past houses or apartments that are just a few storeys high. There are still armies of elderly employed in various fashions as there were before, especially on street cleaning; nowadays also in the many public toilet blocks (which are nicer than they used to be); and there are still many people keeping the peace or being security guards (even though nowadays there are also millions of CCTV cameras as well helping them out and even some robots!)
There is still a lot of green and a lot of trees remain. In fact Shanghai has probably more green than before as they have (proudly) torn down old houses to build new parks all over the city. Some of the older houses have now become cafes and restaurants and bars, but retrofitted in a trendy way.
There is still a lot of buses, though underground of course is now the world's largest subway system with at least 15-20 different lines (15 years ago there were only 2 lines)--though a few new overground train stations exist to support the incredible high-speed train system that has been built from scratch. In fact when I first arrived there were just normal trains and some "fast" trains, known as K (for Kuai or Fast). Then they introduced the T (for Te or Very), and then there were the Z trains and the D trains as the train meanings changed from speed to comfort and incorporated first class (since they were basically all fast nowadays, except for some stopping trains).
There are still people collecting plastic from the rubbish bins to recycle them and get money, and the new push this year for separation of rubbish might have even helped them. There are still people pulling carts around piled up with cardboard and ringing bells asking for people to give their recyclables. There are still some people with their cabinet by the side of the road where they will fix bikes. In fact though I didn't have the chance to be in a downtown area at rush hour in order to see if the number of bikes is the same as it was 15 years ago or not, i would not be surprised if it was similar since the crazy of about 4 years ago with millions of bikes that you can find anywhere (and the app shows you where the available bikes are) to rent for a few pennies for 15 minutes, pay with the app and leave (almost) anywhere too. There is no doubt there are more electric scooters now than there were before though.
There are still small little hole-in-the-wall restaurants selling dumplings (I had to have my fill of the soup dumplings that are a Shanghai specialty and come with either thin or thick crust), even as there are super trendy and expensive restaurants and bars inside and outside of the plenty of shopping malls. It is not unusual to pay 6 British pounds equivalent for a fancy coffee (Sea Salt Black Gold Iced Coffee) though a normal coffee can be got for half of that. In fact money may have been the thing that has changed the most; not just the prices which have increased dramatically and even the dumplings or fruit on the street is about 5 times more expensive than 15 years ago (and of course the cost of housing, education and food is much more expensive, in many cases the most expensive in the world). Nowadays almost no-one has any cash in China, with everything being done through a mobile payment app, and many shops refuse to take cash!
There is a lot more "modern" culture, such as shopping festivals and music festivals (I was there over a holiday weekend so saw a couple in major shopping areas). There is of course Pudong, a whole part of a city that was a marsh 30 years ago, still barely developed 15 years ago and now a highly developed area (bigger than a normal city in the West) with very wide highways, universities, science parks, industrial parks and much more.
There has been a real effort to keep some of the older buildings, indeed some get a new lease of life, like the new Columbia Circle which was an old British Navy club a hundred odd years ago and now is part of a redeveloped area (amusingly you can visit the old swimming pool, but only to look at it from the side, and you must follow the "rules of viewing the scenic pool").
I went back to the Urban Planning Museum, 15 years on, to see the scale model of the city. Nowadays of course there are hundreds, if not thousands of skyscrapers, including the second tallest building in the world, two dramatically bigger airports, several large convention centers, multiple stadiums and much more besides. The museum has many exhibits explaining the development of Shanghai addressing its social and environmental challenges as well as transport and the harder aspects of the city.
