The ordinary letter delivery during World War II were cut off in all the countries involved in the war. A Chinese family of parents and eight children were split different countries, enduring the agony of losing touch with their loved ones. The only means for them to communicate was through the messages delivered via the ICRC. Under the circumstances, each Red Cross letter was limited to only 25 words(or 25 Chinese characters)written in a special form provided by the ICRC.
