55 nah...it's just a middle-aged Chinese woman skinny dipping at night... Wouldn't be surprised if she was performing some kind of cleansing ritual to rid herself of bad luck and/or improve her prospects at marriage, finding herself a rich husband, getting a financial windfall or even ridding herself of an illness. Or maybe she just felt like swimming naked in a sea of filth at night, just as the beached whales love to sit by it in the day...to each her own.
