YangZifan-BA7KVH To be honest, amateur radio is an expensive hobby. Unless you have exceptional receiving capabilities and the ability to build various RF devices (although building these requires equipment that can cost even more than the devices themselves...), antennas, etc., it's not a worthwhile investment. If you just want to chat with others, there are fewer and fewer opportunities for this, especially since communicating over long distances is already challenging. However, if you have the ability to study certain technologies, then this becomes irrelevant. With so much information available online and the internet being so developed, it's not impossible to achieve DX (long-distance communication) within the A-class license range, even over several thousand kilometers, as long as you have the skills and time.
