The English slogan at this train station is obviously wrong, right?

That’s not right.

In my personal opinion, opens and welcomes are both verbs and cannot be put together. Combining the meaning of the sentence, you can use peony blossoms as a phrase, " "Blooming peonies", you can use rich adjectives to describe peonies, such as "flourish" is good. Bloom's parts of speech include verb and noun. I don't know if I can use its gerund form blooming

There is also "welcome" "Olympic Games", you can use welcome, hail, gratulate, greet, note that it is the third person singular form

So:

First addition

Also, one Lou's "Peony flowers blooming with the Olympic Games." I support him, the non-predicate sentence expresses the meaning, but as a slogan, it seems that using a predicate verb sentence is more inspiring

Second addition< /p>

Well, also, it is best to add "Beijing", Beijing Olympics, to reflect the strong support for the 29th Olympic Games in Beijing
