At someone's house How would I say something like the following: "I just ate at the Smith's house," or "I just finished eating at the Smith's house"? I believe the correct way to say I just at is "我才吃了," correct? I just can't figure out how to say "at ____'s house." So, In summary, I'd like to know how to say the following: "I just finished eating at the Smith's house." "I just ate at the Smith's house." 多谢！！

Showing possessoin (的) I have noticed that in some sentences that are showing possession sometimes the character 的 is omitted but other times it is there. Can you please explain when it is necessary to show possession and when it isn't. Some sentences for example that I've seen are below: 我的朋友。 - This is an example of a time when I've seen it present. 他是我男朋友。 - Then I saw this sentence and it leaves out 的. If you understand my question please help me out. Thanks!

你们好，朋友！ 你们好，人人！ 你们好吗？ 我叫 Cody 也我是美国人。 我爱汉语，可是我不说尚未。 Hello, friends! Hello, everyone! How are you? My name is Cody and I'm an American. I love Chinese but I don't speak it well yet.

你们好朋友！ 你们好吗！ (Is this correct?) If I want to say "hello" and "how are you, friends?" to a GROUP of my friends is the way I wrote it correct? Please correct me if I'm wrong in the following: 你好！ = "Hello" (only to one person) 你们好！ = "Hello" (when saying it to a group) 你好朋友！ = "Hello friend" (but this CANNOT mean "hello friends"). 你们好朋友！ = "Hello friends" 你好吗？ = "How are you?" (only to one person) 你们好吗？= "How are you?" (to multiple people) If I understand correctly there isn't any plural form of verbs so there must be a number placed in a sentence to show more than one of something. However, when speaking with/about people you only have to use 们 in order to show that there is more than one person. Thanks in advance for your help!

Why are some words used twice? I have some 豆腐干and on the package it says "香香你的嘴。” first off what exactly does that sentence mean? It seems to be saying that it'll taste good or smell good for you mouth. Second, why is xiang1 (香）used twice in a row? I've seen other sentences with similar repetitions ( 说说， Etc.). Thanks for your help!

您好吗 vs. 你好马？ What type of people would you use the first sentence with? A university professor? Boss? As an employee to customers? Thanks!
