1935 Linghwa (19 Jan) to Tangshan via Kupeikow Remittance and Mail Transfer Bureau, f.w. China Mail issue 4c, tied by Jehol Lunghwa cds with “2nd Year” obliterated by Chunghwa Post afterward. Transit Nanlanchung (20 Jan). Transit Kupeikow with “This Mail is forwarded by our office and all invalid adhesive will be compensated by our office / Kupeikow Remittance and Mail Transfer Bureau” cachet. Arrived Tangshan (26 Jan). Mails between China and Manchukuo were exchanged at Shanhaikwan or Kupeikow. Examples from Kupeikow, however, are much rarer than those at Shanhaikwan. This cachet was probably used only for a few months at the beginning of mail exchange. 1935.1.19 隆化經古北口寄唐山，貼通郵專用票4分，銷熱河隆化三格日戳（“二年”字樣後來被中華郵政塗抹）。1.20經南濼中。後於古北口交換，鈐少見之“此係本局承轉所有無效郵票表示之郵資均由本局賠繳 / 古北口匯通轉遞局印”直戳。1.26抵唐山。往來華滿之郵件於山海關或古北口交換，但古北口的例子遠比山海關稀罕。此指示戳可能僅於通郵初期使用數月，難得。
