Intangible assets include patent rights, non-patented technologies, trademark rights, copyrights, land use rights, franchise rights, etc.

Amortization of intangible assets is a method of amortizing the original price of intangible assets within their validity period. Amortization of intangible assets generally adopts the straight-line method, and is directly credited to the "accumulated amortization" account during amortization.

In this question, the cost of the intangible asset when it is scrapped is 6 million yuan. One reason may be that it has been amortized since it was purchased. The unamortized amount as of now is 6 million yuan.

Another possibility is that the intangible assets have not been amortized since they were purchased. The current 6 million yuan is the cost at the time of purchase, that is, the recorded value.

The description of this question is unknown, so the answer is for reference only.
