On 31st March Jemi and I flew from Shenzhen 深圳 to Kunming 昆明, and then flew on to hot and hazy Jinghong 景洪 in Xishuangbanna 西双版纳, southern Yunnan 云南. Once upon a time this was a twenty-four hour bus ride. The Jinghong city motto should be “Pretty damn tropical !”, it certainly seemed hot and sultry after Hong Kong and Kunming.
