Planning a ~3-week China trip with my wife and our baby

Planning a ~3-week China trip with my wife and our baby, 20 March to 11 April 2027. Mainly interested in nature, landscapes and scenic experiences. Trying to avoid long hikes/high-altitude places and keep the pace reasonably relaxed.

Would love input from people who've travelled China: Would you change anything, or am I missing a must-see destination?

Apr 1: Dali: Erhai Lake + Xizhou
Apr 2: Dali: Cangshan cable car + Old Town
Apr 3: Dali: relaxed day / Shaxi
Apr 4: 🚄 Dali → Kunming → Guilin
Apr 5: Yangshuo: Li River cruise

Apr 10: Guangzhou: shopping / relaxed day
Apr 11: ✈️ Guangzhou → Bangalore

We've already dropped Jiuzhaigou and Lijiang mainly due to altitude, and Huangshan because of the amount of stairs/walking.

What would you change? What am I missing that is genuinely worth adding, especially for nature/scenery?

Wuyuan, Longji, Fenghuang, Luoping, Guizhou, Hangzhou etc. are on my radar. Should I consider any of these?

Thanks!
