Asking about someones family: Asking if someone has brothers or sisters

💬 在 on its own means "to be in or at" a place, so no 是 is needed. Add 吗 at the end to turn any statement into a yes/no question.

💬 The place goes before the action: 在 + place + verb. You can reuse this pattern: 她在北京学习 "She studies in Beijing".

💬 独生子 literally means "only-born son". A woman would say 独生女 (dú shēng nǚ).

🇨🇳 Because of the one-child policy, many Chinese people born between 1980 and 2015 are only children, so this answer is very common and needs no explanation.

💬 Besides meaning "one person", 一个人 also means "alone" or "by yourself" when it comes before an action: 我一个人吃饭 "I eat alone".

💬 Here 那 means "so" or "in that case", picking up on what the other person just said. 会 adds the idea of "would" or "tend to".

💬 无聊 can describe both a bored person and a boring thing: 这个电影很无聊 "This movie is boring".

🇨🇳 还好 is a modest, noncommittal answer, like "not bad". People use it to play things down instead of complaining or showing too much enthusiasm.

💬 很多 can go directly before a noun without 个: 很多朋友 "lots of friends".

💬 表 marks a cousin through your mother, or through your father's sister. Cousins through your father's brother use 堂 instead: 堂哥 (táng gē).

🇨🇳 Many only children grew up close to their cousins and often call them "brother" or "sister", so cousins fill much of the role of siblings.

💬 真 + an adjective makes a quick exclamation: 真好 "so nice", 真累 (zhēn lèi) "so tired".

💬 In this sentence 得 means "must" and is said (děi), not the usual (de).

💬 Put a time before 见 to say when you'll meet again: 下午见 "see you this afternoon", 周末见 "see you at the weekend".
