The oyster sauce you use can later for fried rice. Its what makes restaurant fried rice taste the way it does...I get LKK Premium Oyster Sauce or MegaChef. LKK has several but there is a huge difference in quality.
The Chu Huo paste is great for a beef and radish stew. That is one of the main dished its used in. Its more or less like beef stew but with radish instead of taters. You could use taters if you wish.
Look for LKK Double fermented soy sauce or the LKK Premium Dark Soy. Both are really good soy sauce. Kkikoman reduced sodium Tamari is also really good for a soy sauce.
The red fermented bean curd though is the "secret" ingredient and the hardest to find. Its little tofu cubes in a RYR and wine mixture. Mash a couple cubes with a fork with some of the liquid in the jar.
