Lin points out that even if these old recordings had all been issued overseas in the 1960s, when one looked, the masters could never be located. Even if every one of them had written on them that they were produced by China Records, they could never be found at China Records in Beijing.
林谷芳指出，儘管這些老版本在六○年代，都已流傳海外，但要找原始母帶時卻找不到，儘管都寫著中國唱片公司錄製，在北京的「中唱」卻找不到。
