Currently known world record certification institutions: Guinness World Record, Onison World Record, WRCA World Record, Flag-raising World Record, World Record Certification Association, American World Record Society, Singapore World Record Book, Indian Elite World Record, etc. What I want to say is that every one is true, because others are their own brands and have never imitated others. It's like Hermes and hello House. The product forms are similar, but the brands are different. People are their own brands.
