How to get from Kunming downtown to OCT Hot Spring Water Park?

Seeing the following two routes from their official Weibo, Kunming people are looking forward to it. This hot spring water park is near Yang Zonghai, not far, much closer than Chengjiang, and it takes about 40 minutes to drive from downtown Kunming. I heard that there will be a special bus in the future. There are two self-driving routes: ① Kunming main city-Kunshi Expressway-Tang Chi exit-Yunnan Overseas Chinese Town (take the second exit in Tang Chi); ② Main City of Kunming-Kunshi Expressway-Wang Jiaying Exit-Kunshi Highway-Yunnan Overseas Chinese Town.
