What is the first half of the following lines?

The first half of these poems are as follows:

1, the green hills cannot be covered, after all, they flow eastward.

There seems to be no one on the empty mountain, but I think I heard a voice.

3. It's not that chrysanthemums are favored among flowers, especially in bloom.

It's better to hold the incense on the branch and wait for death than to blow it into the north wind.

5, with this beauty, outstanding is frost.

"Castle Peak can't be covered, after all, it flows eastward" comes from the work "Bodhisattva Man, Building a Wall in Jiangxi Province" by the famous Song Dynasty star Xin Qiji. The original text is: How many pedestrian tears did Yugutai fall into Qingjiang River? Looking at Chang 'an in the northwest, there are countless poor mountains. Castle peak can't cover up, after all, it flows east. In the evening, the river is gloomy and there are partridges in the mountains.

How many pedestrians' tears are there in the running water of Yugutai in Ganjiang River? I look up at Chang 'an in the northwest, but unfortunately I only see countless green hills. How can Qingshan stop the river, and the vast river finally flows eastward. At dusk by the river, I was filled with sadness when I heard the sound of partridges coming from the deep mountains.

Extended data:

"There seems to be no one on the empty mountain, but I think I heard a voice" means that there is no one on the empty mountain, and I can only vaguely hear the voice in the distance. It's not that chrysanthemums are favored among flowers, that is, bloom has no flowers at all: it's not that chrysanthemums are favored among flowers, but that you can't see better flowers after chrysanthemums bloom.

The original text is: autumn shrubs are like Taoist priests, and the more they are surrounded, the more inclined they are. It is not that chrysanthemums are favored among flowers, and this kind of bloom is not without flowers. Clusters of autumn chrysanthemums surround the house and look like the home of the poet Tao Yuanming. Looking at chrysanthemums around the fence, the sun will set before you know it. It's not because chrysanthemums are favored among flowers, but because they can't see better flowers after blooming.
