Chinese ginger jars

These are Chinese ginger jars left to me by grandmother who died in the 1980s. I believe they were collected individually rather than as a set. Each has a twin circle mark on the base. The larger jar has an additional mark that looks a little like bird footprints. Or it may just be a flaw. The lid of the large one was unfortunately cracked and roughly re-glued before it came to me. Otherwise they are in good condition.
