Is “Killed by the people of Cai; usurped and murdered by Prince Tuo” true?

In the official history, the one killed by the people of Cai was Duke Fei of Chen (Prince Tuo), whereas in the romance, the one usurped and murdered by Prince Tuo was Crown Prince Mian. The source mistakenly attributes the deeds of these two to Duke Huan of Chen, which is a serious case of misattribution and confusion of settings. The original text: 「蔡人为佗杀五父及桓公太子免而立佗」（《Records of the Grand Historian·Hereditary House of Chen and Qi》, data/raw/shiji/陈杞世家.txt）
