有些人穿着汗衫，但大多数人都是打着赤膊。

Some wear singlets, but the majority are stripped to the waist.

图为一男子赤膊走在“城中村”在一个小巷。

Pictured is a male shirtless walk in the "Villages" in an alley.

个人而言，对于那些大热天赤膊跑步者我没什么意见。

Personally, I don't have a problem with shirtless runners in the hot weather.

不单是热食、生活物资、红包，看到双眼失明又打赤膊的街友，志工赶紧送上衣物。

Apart from delivering hot food, daily supplies and red envelopes, upon seeing a blind man without a top, volunteers quickly give him some clothes.

我确信那些赤膊跑步者也认为这样能帮助他们避免乳头摩擦，也不会有经典的T恤晒痕。

I'm sure men who run shirtless also appreciate that it helps them avoid nipple chafing and the classic runner's T-shirt tan.
