I think of a subtropical climate with hot long humid summers, with mild to chilly but short winters, such as where I live (Rock Hill, SC)
Yeah, I'm familiar with that area being a Carolina boy (raised in a military family so I did live overseas as a kid and in other parts of the US, but raised mostly in SC & NC). I went to college at UNCC in the early-mid 2000s and have family in NC and all over SC.
I would say that Rock Hill, with a stable winter, could be subtropical and I would say that for most of the southeast (inland areas included) if we had the geography and teleconnections that prevent us of constantly getting high winter temp abnormalities (20F+ below average temperature abnormalites) via potent Canadian highs and polar vortexes that make themselves down every now and then.
I'd consider a climate more subtropical, if it's environment has higher levels of winter ecological activity - climate and environment can never be separated.
When I think of subtropical, I think of South African Indian Ocean coast climates from about East London northwards. Warm to hot summers and mild to warm winters, not as hot as the tropics and with more seasonality in temperature than most tropical climates but less than most oceanic ones.

Are you sick? HARBIN is considered subtropical climate???? It is one of the coldest cities in the world!
Winters are extremely cold and long, highs are well below -10C in January, colder than most Canadian cities(Toronto, Montreal, Halifax) from November to March.
Summers are warm and short with an average high below 30C in July.
If Harbin is subtropical, then Vancouver, London, Paris, Berlin, Amsterdam and Moscow are all subtropical.

I agree for the most part. However, you do have to factor in the night temps, it may average in the upper 60s and low 70's during the day in the cold months - but it may average below 50F (in the 40's in this case) at night - and then usually you need a jacket and some people require heating at those temps. That being said, I do think if the daytime temperature averages above 70F (I personally would say 72F and up) during the coldest months, that when you reach tropical or megathermal (I like the latter word better) territory with the climate.
What I would say what would say one of things that would disqualify a climate to be too cold to be subtropical if any day of the year (outside of once in a few decades or century event) where the temperatures fail to go above freezing. Raleigh, for example, averages around 3 days a year that it doesn't go above freezing. I seen Tom77Falcons on this forum mention that could put many subtropical flora under serious threat, which I agree.
Yes, tis true. I've said many times that there is a continental feature to eastern US climates in the south. Say southern GA for example. It has daytime highs averaging over 60F in winter, but the nightly lows also go down 20F to say low 40'sF. A 20F swing from day to night seems pretty continental in winter. Also seasonally, an avg winter low of 40F vs a summer low of 75F seems pretty continental.

I think he meant to say Hainan and accidentally typed in Harbin . Hainan has a climate identical to Louisiana
I'd say long hot summers and short, relatively mild winters with little snowpack.
I think the entire deep south is unquestionably humid subtropical while states like Kentucky and Virginia are transitional.
I live in Augusta georgia and I think it is pretty much a quintessential humid subtropical climate, very muggy tropical-like summers and short mild winters. Winter snowpack is just not a thing that happens here, we rarely get snow, almost a decade can pass without snowfall.
There's also a delay when fall and winter kicks in, most deciduous tree's leaves won't start changing colors until November and they can start blooming in January(that happened this year).
Koppen described a warm moist climate and snowy, cold winter climate, this what is meant by the later terms like humid subtropical and humid continental. You have to reliably get annual winter snowfall in the first place to even be a contender for continental.

Exactly, for example in Raleigh, NC, the average high is 52 in January and Average low is 34 (per Weatherspark) = 18 degree difference between highs and lows = pretty continental. Actually, after living in NC for 27 years and Raleigh for 13, it's VERY common to have temp swings over 20F (30F temp difference between the high and low temp is not rare here) in the winter and most of the year really. Raleigh winter lows are from the upper 20's to low 40's and the summer lows are in the 60's to mid-70s, so yeah you right about this continental stuff. This actually true until you get to South Florida (interior South Florida is pretty continental - not much less than other Southeastern states - Miami is less continental but more continental than the average "tropical" climate as people often claim Miami is tropical)
