"Siyuan Soft Black" is a rounded font developed by a Japanese person, who modified the open-source Siyuan Black font. It is available for free download but because it was developed by a Japanese person, some Chinese characters cannot be displayed, such as the "cha" in "chá", which is not able to be shown. This is also the reason why it is rarely shared by Chinese people, However, it is a good choice for titles with fewer characters, Siyuan Soft Black has three styles, from small round corners to large round corners, etc.
