This is a free and open-source vector drawing software that supports Windows, Mac, and Linux platforms, with a portable version and support for 64-bit computers. The best part is that it has a traditional Chinese version. Because it is open-source software, development and updates will be stable. It can edit Adobe Illustrator AI file format and CorelDraw CDR files. Additionally, it's worth mentioning that to move the hand-held drawing board (tablet), it is not the spacebar or the H key, but by holding down the middle mouse button and dragging.
