The People's Republic of China initially adopted a similar square seal, but this fell out of use by 1954. Several seals have since been claimed as the lost Heirloom Seal, but none have held up under scrutiny. In at least one case, the seal concerned was found to be a personal seal of an emperor, rather than the Heirloom Imperial Seal.
