Mooncake Festival level 3-1 (formerly level 2-16) is a bit difficult since you must sacrifice accuracy for distance. Our strategy is to loft the first Yellow bird and speed boost through the pig hanging from the balloons. With a little luck, the whole right side of the level will collapse. With the next Yellow bird, shoot straight into the trio of boulders. They will roll down the hill onto the TNT and the launched pebbles could pop the remaining pigs. If necessary, there are a few more Yellow birds. The score in the video below is 112,880.
Note: In a recent update, the level numbers were changed from Level 2-16 to Level 3-1.
