翻译一下：墙内开花墙外红

①Red flowering wall wall
②In the wall blooms outside the crenellated wall red
③The outside of the efflorescence wall inside the wall is red

In the wall blooms outside the crenellated wall red

Bloom outside and red inside.

就像桃花什么的树枝很长，延伸到了墙外。所以虽然是种在围墙里面的树，墙内开花了，墙外也能看到那个花，而且花掉落在地上的花连墙外的地面也红了。我想应该是这样吧

楼上的翻译果然非同寻常…… 厉害！佩服呀！
