her respect when Chan Pei Mui with sister Chan Pei Aap joined her, Yam renamed her troupe ("梅"花艷影劇團) in deference to her former boss who also shared male lead status with Yam in this troupe. The three of them offered the female version of Kwai Ming Yeung (Yam), Sit Gok Sin (Mui) and Ma Sze Tsang (Aap), Tsui Yan Sam (徐人心) as female lead, and kept building up an even stronger fan base on what Yam already accumulated in Macau. Portugal owned Macau during the Second World War and it was neutral during the conflict. Japan's respect for that neutrality made Macau a safe haven for migration from elsewhere otherwise occupied by Japan. Population in Macau went up significantly as a result. Their support for performances made life relatively easy for performers. (Depending on individual performer's pay grade, some were paid in a less volatile currency. The top-billed (female lead) Tam Lan Hing, arrived in Macau in late 1942 and eventually gained weight in those years, was rumored to get one tael of gold for a day of performance.) Ma Sze Tsang formed the first Hong Kong troupe with both actors and actresses in 1933. Records show Yam's all-female troupe was the last one still doing well in theatres since then. For ten years (1935-1945), Yam made Macau her home, when her hometown in Guangdong fell to the Japanese during the Second Sino-Japanese War. Meanwhile, she moved her family, including her (Chinese custom, actually paternal first cousins.) younger sister Yam Bing-yee () into her new home in Macau. Occasionally, Yam in 1939 renamed that same all-female opera troupe (「鏡花艷影劇團」/高陞戲院/紫雲霞/《夜出虎狼關》郎紫峯=郎筠玉) to perform in Hong Kong or in 1942 travelled to perform in Guangdong with Hung Sin Nui's Sifu (何芙蓮) as the co-star. Hung met Yam that year. In Macau, she met the major contributors to her career, two very important men and a married couple through the two brothers who eventually became the troupe manager () and librettist (). One man became her godfather and vocal style tutor while the other man helped manage her finance and held the purse strings at times, looking after the war chest Yam built up in Macau. Theatres in Hong Kong Yam was the male lead in many Cantonese opera stage productions, in Macau initially and in Hong Kong since 1945, opposite many actresses, including Sheung Hoi Mui (上海妹), Che Sau Ying (車秀英), Tam Lan
