On the 9th of November 1984 there was a preview screening of "The new adventures of Chor Lau-heung" was held at Shatin International City and many pictures were taken of Yung Mei Ling. On that day, there was an exterior scene with Yung Mei Ling, Yam Tat Wah and Chow Sau Lan, as only the three of them were in historic costumes during the presentation. The corresponding scenes were in episodes 37 and 39 of the serie, where Yam had the same clothes and Yung Mei Ling the same headdress. The scene in episode 37 was shot on November the 9th as the position of Yung Mei Ling's head jewellery feather is exactly the same as during the presentation.

1984.11.9《楚留香之蝙蝠传奇》试映会在沙田国际城举行，阿翁拍了很多美照。当天有阿翁任达华周秀兰三人的外景戏，因为只有他们三人是古装。对应的是37,39集外景戏，任达华应该换了衣服，阿翁应该换过头饰。这里任达华扮演的原随云起了色心，像欧阳克一样解桑小静的衣服。总之，可以完全确定11.9日拍摄了37集的外景，阿翁头顶首饰羽毛的位置完全一致。
