Chinese dramas take way too long to air so I have stopped watching them. Plus, if a lead gets into a scandal the whole drama pretty much get axed before it even airs. Idk how Chinese celebs do it, their dramas get aired 3-4 years after filming, I think thats unfair and ridiculous. Chinese dramas pretty much just like to capitalize on what is currently trendy and who is popular. Its all about $$ for Chinese dramas so the stories aren't that good. Honestly, Chinese entertainment news is more exciting then actual Chinese dramas.
Korean dramas are most advanced in storytelling, cinematography, music and directing. However, they tend to jump on one trend for a long time and all the stories become quite similar with a touch of fantasy or family drama.
