"logo" as a variant of "Logo" has a long history. It existed before the first heteronym was published. The Dictionary of Modern Chinese (ISBN17017.91), compiled by the Dictionary Editorial Office of the Institute of Linguistics, Chinese Academy of Social Sciences, was published by the Commercial Press. Modern Chinese Dictionary (Revised Edition) published by 1996, although "logo" and "logo" are not printed in one entry, it is marked "also used as logo" after the entry of "logo"; After the "logo" entry, mark it as "the same logo".
"Sign" and "logo" are equivalent in modern Chinese. But "logo" and "logo" do not represent "knowledge" and "ambition". Modern Chinese Dictionary divides "zhi" into three items because it is similar in shape and sound, but it needs to be treated separately in meaning. Only in the third entry of "Zhi" has the same annotation as "Zhi (Zhi)". Only this "ambition" meets the definition of "logo". From this perspective, "logo" seems to be more accurate in meaning than "logo".
