the PRC government never uses this character in official documents, but uses 万亿; wànyì or 太; tài; 'tera-' instead.
This is too broad: PRC official documents do use the character “兆”. PRC legal metrology documents list 兆 as the SI prefix for 10^6, and other official documents use forms such as 兆赫 (MHz).
Full reasoning
The article says the PRC government never uses the character 兆 in official documents. That is contradicted by PRC official materials.
- A State Council–published copy of 《中华人民共和国法定计量单位》 includes 兆 as the legal decimal prefix for 10^6.
- More recent PRC government and government-issued standards also use 兆 in official terminology such as 兆赫（MHz）.
So while PRC usage may avoid 兆 for some large-number contexts because of ambiguity with 10^12, the blanket statement that the PRC government never uses this character in official documents is false.
