How to understand: The marriage was set in that year, when the breeze and the bright moon were just at that time. Shuang Ling proudly studied pine branches, and the phoenix flew to the mountain branches.
This beautiful marriage that fits so well is actually set in a previous life. This is a beautiful time when the wind is clear and the moon is clear. The pine and cypress standing proudly in the snow and wind are so lush that the phoenix flies to the branch where it will sleep.
It means that this marriage is beautiful, and every place fits so well. Secondly, parallelism and metaphor describe it more vividly and concretely.
