I want to know the answer to the following question:
Who took over from Tongzhi?
All the background I'm provided with is that "She entered the imperial palace in the 1850s as a concubine to the Xianfeng Emperor (r. 1850–1861) and came to power in 1861 after her five-year-old son, the Tongzhi Emperor ascended the throne.". Is that enough to answer the question?
Answer: no
