Learning and expanding vocab with a fluent speaker

Are there any classes, possibly but not confined to learning more vocabulary without learning how to write. I’m a fluent speaker who grew up in Taiwan from young age, so my vocabulary is somewhat limited at times. I’m pretty busy, so I’m not looking for a class where I need to learn to write and start over. Just improve my vocabulary to articulate myself better.

I thought you said you were going back to study in the US in some other post?
Anyway, if you’re busy, then you might want to try online tutoring:

Or some other online resources:
fluentu.com/chinese/blog/201 … -podcasts/
chineseclass101.com/category … ?order=asc
openculture.com/free_mandari … se_lessons

Or use some sort of app or online tool like these:

I am moving back in the spring. But I want to eventually work for an muti-national corporation and Investment banking. Having a more articulate command of mandarin will really help.

italki.com and get a “community tutor”, not someone who holds themselves out as a teacher. All you need is to set a topic each day, prepare something on your own, and get corrections. I’m assuming your grammar is native-like already.
