@Li-Xiao Can you send me the font used in this example. I could not replicate the problem with the fonts I have.
I only have around twenty Chinese fonts installed on my computer. After testing, only a few of them stay on the baseline, while the vast majority shift off it. These same shifting fonts do not deviate from the baseline in Illustrator or CorelDraw. Here are the download links for two free for commercial use Chinese fonts that reproduce this offset for your testing.
