How to travel from Shenyang to Kunming to 980 yuan?

Because this is a shopping group, and the round-trip train ticket is over 1000, how can it be so cheap? You also need to eat, drink, ticket, visit, etc. Think about whether this money is enough? Yunnan natives travel at least 1600 yuan -2000 yuan, not to mention our northeast! Last year, I spent 3688 yuan on a tour group in Kunming, Yunnan, but I still feel that it is not enough. I paid for it myself 1800 yuan barely built it, 980 yuan? Don't be cheated! Travel is for fun, don't come back with a full stomach! If you really want to go, don't trust the low-priced group.
