I'm not sure if there are better shops, but I've been to Syntrend Creative Park and they have a floor with all kinds of gadgets, including various keyboards. There are mechanical keyboards to try out (IIRC there are for example ducky keyboards), and they are also selling some good keycap sets.

Yeah, this is a US issue. If you go to Tokyo or Taipei, you will find physical stores in cities with many different kind of mechanical keyboards.

Turning character into pinyin introduces so much ambiguity and lose so much information at local level that we need to go back and forth multiple times to infer what that word really is according to the partially parsed part of the sentence. While written sentence in character we don’t even need to do linear character by character scan, usually a glimpse of it will give you most of what you need to understand it.

This is cool! This will save a lot of time to convert a hand-drawing into high-quality digital contours for adding colors and post-processing on a computer.
