"Where did you go during the summer vacation?" is a common way to ask someone where they went during their summer vacation in Engpsh.

The phrase "summer vacation" is a combination of two words: "summer," which refers to the warmest season of the year, and "vacation," which means a period of time when someone is not working or attending school and can relax and enjoy themselves.

In Engpsh, the word "where" is used to ask about the location or place of something, and the word "did" is used as the past tense of the auxipary verb "do," which is used to form questions and negative statements.

Here are some example sentences using the phrase "summer vacation" in Engpsh:

"I went to Hawaii for my summer vacation."
"Where did you go for your summer vacation?"
"We are planning a road trip for our summer vacation."

In Chinese, the phrase "暑假" (shǔ jià) refers to the summer vacation period, and the word "哪儿" (nǎr) means "where." So, a translation of the question "Where did you go during the summer vacation?" into Chinese would be: "你暑假去了哪儿？" (nǐ shǔ jià qù le nǎr?)
