Do Chinese People ever say 你好吗？
I have seen 你好吗 taught for "how are you" in more than one place, but heard a video where a person in China said you NEVER hear this in China. If Chinese people don't say this, what are the most common expressions that they use for "how are you?". The same video said that Chinese people really don't use these small talk introduction phrases so common in the West. They just directly say what they want to say. Is this true?
I am no expert, but on a channel I follow about Chinese (in Spanish), in a video about "basic greetings", she (from China) and another guy (from Taiwan) said that they do not actually use it, according to her they only ask when they are close to someone and are actually interested in knowing, also they will also ask about the specific matter (how is your health, how is your business, family, etc.), and not a generic "how are you?".
So, I am assuming it is true that 你好吗 is not actually used, or at least not in the same way we do use "how are you?".
Video for reference (in Spanish), about second 0:35: https://www.youtube.com/watch?v=iCFGSEmXrTk
as a native chinese speaker, i agree with what is said on this video. 你好吗 the expression does exist in chinese, but it is not commonly used.
my guess (i wasn't realizing we seldom use “你好吗” before i saw your post): it is widely taught to non-native chinese speaker, i guess it's just because it is the closest equivalent of "how are you?" in many ways (but not in the frequency of usage) you can find in chinese. they are both three words sentences and "how" sounds like 好. a better translation should probably be “（最近）（你）怎么样啊？”
I've only been learning Chinese for 6 months and haven't come'n very far in my vocabulary yet, but I also have a physical teacher called Tang ting, she's from China and taught me a lot of good information about the language, as for example that you use different greeting phrases in different provinces. In the province where she comes from (don't remember any of the provinces names sorry) they say "你好吗" when asking "how are you". Meanwhile in the more south east provinces they use "你吃饭了吗" which apparently is more of a traditional way of asking for someones well being :)
The video posted above by DexRed made by native Chinese teachers would contradict what you say here. They say what you don't say is 你好吗, what you say instead is 怎么样？都好吗？and that you can use 怎么样 with everything, for example 你家怎么样？你工作怎么样? Etc. Although they do state that a generic "how are you?" isn't really used in Chinese.
It is in Spanish, but they are both native speakers and the Chinese is shown on the screen.
