This pattern is used in formal written Chinese to express that something will happen at a specific future time. “将” marks the future, and “于” introduces the time point.

“于” is a formal preposition meaning “at,” “on,” or “in.” It is common in news, announcements, and written reports, and is often used before time expressions.

“并” links two related actions in formal style, showing that the second action happens together with or in addition to the first. It is more formal than “和” or “然后.”

In Chinese, a verb or verb phrase can modify a noun by adding “的.” This creates a descriptive phrase before the noun, similar to a relative clause in English.

A time expression is often placed at the beginning of a sentence to set the time background for the whole event. This is a very common Chinese sentence structure.
