This is good advice. And this is true even once you become a professor. All time spent on teaching will go against your career progression. Even if you're tenured and don't care about promotion, you'll feel like an imposter in your department if you're not somewhat competitive research wise.

Generally speaking, there's no recognition in teaching in general, and at university level it's often not even considered as a job by itself.

Maybe it's different in Asia, but that was my experience in the western countries where I worked.
