In 1978 I received a letter from Captain L.H. Williams who was commander of the Chinese Maritime Customs until 1949. He listed eight former US minesweepers in his unit:

Customs Preventive Ships

AM 153 Fei Hsing A1 Buoyant
AM 217 The Hsing A2 Delegate Yung Ho
AM 225 Ho Hsing A3 Elusive Yung Kang
AM 226 Yun Hsing A4 Embattle Yung Hsing
AM Tu Hsing A5
AM Hsiang Hsing A6
AM 363* Hung Hsing A7 Gavia Yung Chun
AM 279 Jung Hsing A8 Prime Yung Feng
*May have been AM 262 Marvel.

As you will see these designations do not match the accepted names in the Chinese Navy.
AM 217 Delegate was named Yung Ho
AM 226 Embattle was named Yung Hsing
AM 363 Gavia was named Yung Chun
AM 279 Jung Hsing was named Yung Feng

I have not seen these names and numbers anywhere else and it would be interesting if anyone has further information.
