Has anyone else tried the learning Chinese method

After learning Japanese for a few years I started taking Chinese courses for a year and a half—I’ve found that the process of learning Chinese has inexplicably increased my vocab, recall, and reading speed in Japanese as well. Remembered onyomi readings is much easier because I have the built in clue mnemonic of the actual Chinese reading. The only issue is not recognizing characters between shinjitai and simplified Chinese. I honestly expected that learning Chinese would make it harder, since the readings and meanings of characters in each language would override each other, but that remarkably hasn’t happened. Has anyone else experienced this?
