TONG-4

('tong' in the fourth tone)

There are two sound-determining components often seen in characters that are spoken as 'tong'. One is an important independent character in itself: 同 = tong(2) = same, similar. The other one exists, but is irrelevant as an independent character: 甬 = yong(3) = a river that flows through the Chinese city Ningbo

痛 = pain, ache
