My English is poor.
The picture looks indistinct.
The letter "S" in the word " CHANGSHA " ,form the picture, isn' t like exact "S ".
And I don't think the word is " CHANGSHA ".
I am be weak in cancellation. So my objections are inaccurate.
But I am not sure all Chinese character are fixed in cancellation.
The SHEKLUNG is “石龙” in Chinese.
And the "2" must be a letter more than be a number on the possibility. Look at it, that don't like 2.
I infered it is an upside “S”.
