里程碑！米切尔生涯三分命中总数达到1700个（米切尔命中生涯第1700记三分，达成里程碑）

Avoiding number claims

I need to be careful about claiming specific numbers. It might be good to ask if the user wants a quick graphic, career breakdown, or a blurb to provide options. Since this isn't a coding task, I can keep the output short and straightforward.

For a milestone update, I can say that since his rookie year (2017-18), Mitchell averages around 3.0 made threes per game with a career 3PT% of approximately 36.7%. I should highlight his impressive performances, like his 71-point game where he made 7 out of 15 threes.Crafting a concise message

I should avoid minor details but mention the "生涯71分之夜" to highlight his shooting prowess. While numbers should be minimized, mentioning the 71 points is factual and safe. I can include a fun comparison about him joining the NBA's 1700+ three-pointer club, which is quite generic.

I want to celebrate his achievement and offer options. If the user wants more details, I could mention stats like rankings among active players or season splits without needing to fetch external data. Let's keep it friendly and straightforward!Creating a congratulatory message

I need to make sure my response isn't too wordy. I’ll follow the formatting guidelines for the final answer, keeping it in plain text. A good start would be a header like "恭喜里程碑" to celebrate the achievement. The message should be concise yet warm, focusing on acknowledging the milestone without unnecessary details. It'll be great to keep it straightforward so the user can easily understand and appreciate the message!
