To piggyback michael's post, currently there appears to be gov. agencies in Yunnan promoting domestic travel. 20% discounts on rail fares and Qunar app has been offering generous air promotions (via "manghe" chance boxes), perhaps with subsidies, such as FREE one-way flights (excluding airport tax) from Kunming to Tengchong. That's a savings of 300-400 rmb. Otherwise, high speed rail may take 4 hours to reach Baoshan with additional two hours in bus/car travel time to reach Tengchong in a ~430 km journey near the border.
Because you specifically mentioned hot springs, the geothermal hot spring and geyser scene in the volcanic fields of Tengchong (just 40 km from Myanmar) is touted as being one of the best in Mainland China, let alone in Yunnan. Definitely something to look into if you're fond of onsen.
Btw, I may have made a mistake in my previous post. The new rail from Lijiang to Shangrila may turn out to be a high speed rail after all given the short travel time of one hour or so.
For a limited time until June 26, 2022, the 66th top floor observatory will be open to public for free. Visiting hours: 14:00 - 21:00, weekends and holidays. One of the best breathtaking views of the cityscape. Great for family. Below the skyscraper is intersection of MRT Line 3 (pink) with Line 2/1.
For those following the tragic saga of the baby calf elephant (born at Kunming Zoo), who was forcibly separated from its mother to perform as solo act elsewhere for profit, there's finally some good news. After months of social media uproar and complaints over the cruel treatments of the calf in tears during training in leaked vids, the calf is soon returning back to our local zoo. The visibly depressed mother and calf will soon be reunited after a brief quarantine period. One extra star for the zoo for adhering to the voices of the public. A step in the right direction. More compassion for our animal friends in captivity.
