I want to know the answer to the following question:
What mausoleum is in Nanjing?
All the background I'm provided with is that "It has been serving as the capital city of Jiangsu province after the China was established, and is still the nominal capital of Republic of China that accommodates many of its important heritage sites, including the Presidential Palace and Sun Yat-sen Mausoleum.". Is that enough to answer the question?
