How to go from Chengdu to Myanmar is safe and economical?

First, take the train from Chengdu to Kunming. If you want to save money, take a hard seat, and then take China International Airlines flight to Yangon in Kunming. Of course, you can also take a bus from Kunming to Xishuangbanna, and then transit Myanmar according to where you want to go.
