It is as I understand it very difficult to get full citizenship if neither of your parents are themselves Chinese nationals.
You can get permanent residence status which is similar to citizenship but you have no political rights (can't vote, can't participate in certain processes, can't join the communist party) by marrying a Chinese national and also through a naturalization process after living there for a significant amount of years OR having significant technical knowledge in a highly desired field. This is what most people would consider good enough as short of high crimes you're not really subject to being deported and have most other non-political rights Chinese nationals enjoy.
It might be slightly more likely if you have the means to immigrate to and apply for citizenship with the special administrative region of Hong Kong though you'd still need to live there for many years and/or marry a national to succeed. Quite honestly unless you have existing connections there or can get a well-paying job in the city I'd recommend against putting all your hopes in it as the cost of living is quite high and it could be challenging and the advantage is likely to be minor (like going to the more lax DMV in your area for a driving test).
You'll need to understand both reading, writing, and speaking a recognized language such as Mandarin and be able to integrate into society so this is a process of many years. You should get started learning the language now if you have an interest in residing there long-term in any form.
It's definitely possible but it's a path of many steps and you should be prepared to accept having only permanent residence status as the possible end-point.
Not even a choice.
If you choose over 100F you will see electronics failing more often, working harder, less efficient, working badly, etc because the heat is causing them to throttle in various ways. In the modern world it is far, far easier to heat up a space with a house full of electronics and humans than it is to keep it cool. The energy required to raise the temperature from say 5 degrees F to a more comfortable 40 degrees (35 degree change) pales in comparison to the energy required to keep yourself and your devices cool a mere 10-15 degrees less to around 90 degrees which is still uncomfortably hot and sweaty.
I'll note that a constant 100 degrees is more than hot enough to cause various foods, medications, substances to break down and go bad. Check your medicine cabinet, most of your pills including over the counter are only rated for storage at up to 86 degrees. Your medicine will lose efficiency or go bad in some, perhaps many cases. Your food outside your fridge will spoil more quickly, mold and bacteria will grow more quickly and readily. Your fridge itself will work harder and die sooner.
The tap water will run hot or warm most of the time meaning a shower won't necessarily cool you off much.
The colder temperatures are cheaper all costs considered, feel better, can be negated at a moment's notice with socks, a jacket, and a blanket.
It's easy to insulate a home against extreme cold and just retain heat you generate inside including by your body and devices. It requires a lot more effort to keep the inside cold when both the outside and things inside are generating heat and trying to warm it up.
This is a reason why climate change is a nightmare not just for human comfort but on so many levels. Our electronics are going to operate less efficiently in a warmer world and draw more power to do so.
