The best cookbook for you I think is <em>Phoenix claws and Jade Trees</em> by Kian Lam Kho. Almost half the book focuses on proper techniques and even the recipes are organized accordingly as opposed to the traditional, unhelpful, Western "appetizers, mains, etc."
I've been cooking recently from Kian Lam Kho's Phoenix Claws and Jade Trees. Super delicious recipes, lots of basic instruction and techniques - a great intro to Chinese cooking.
I've been having a blast lately with Phoenix Claws and Jade Trees. It focuses a lot on technique and has few enough recipes you could probably make it through in a reasonable amount of time.
Phoenix Claws and Jade Trees is a good book about the techniques and fundamentals of Chinese cooking.
Other than that, I think /u/spire88's comment is excellent. I can vouch for Chinese Cooking Demystified, and the author of those videos posts on Reddit from time to time (/u/mthmchris)
Since it's from a cookbook, I don't think it's OK for me to post the recipe. It came from Phoenix Claws and Jade Trees. https://www.amazon.com/Phoenix-Claws-Jade-Trees-Techniques/dp/0385344686/
I found this recipe, which is extremely close. https://omnivorescookbook.com/lions-head-pork-meatballs
