BY2 sisters, Miko and Yumi, have undergone a transformation akin to the metamorphosis of caterpillars into butterflies. Their name change from BY2 to Sun Huan and Sun Yu has left many fans scratching their heads, wondering what prompted this drastic shift.

In 2019, the duo announced that they would be leaving their previous management company, Sea Butterfly Music. This move was seen as a bold step towards independence for the two sisters who had previously been under contract with the label since their debut in 2007.

The name change was met with both praise and criticism from fans and critics alike. Some saw it as an opportunity for the duo to reinvent themselves and start anew while others felt that it was unnecessary and may impact their career negatively.

But what about BY2's connection to Wang Lihong? The rumors surrounding Wang Lihong's infidelity were brought up once again when Lee Lianli reported on her alleged relationship with BY2. However, these claims were later proven false when BY2 took legal action against those spreading such rumors.

Despite this controversy, BY2 continues to thrive in the entertainment industry. Their latest album has been well-received by fans who appreciate their unique sound and style. Whether or not you agree with their decision to change names is irrelevant - what matters most is that they continue making music that resonates with people around the world.

BY2的姐妹花，米科和尤米，就像蝴蝶从蛹中飞出的过程一样，经历了巨大的变化。他们从BY2改名为孙涵和孙雨，这一决定让许多粉丝迷惑不解，想知道背后究竟发生了什么。

2019年，由于管理公司合约期满，他们宣布离开原来的工作室海蝶音乐。这是一个大胆的步骤，让这两位姐妹在独立之路上迈出了一大步。

他们改名的决定得到了部分人的认可，也遭到了批评。有观众认为这是一个重生、重新开始的机会，而另一些人则认为这种改变是不必要的，并担心这可能会对她们的事业造成负面影响。

但说到BY2与王力宏之间的情感纠葛，那个关于王力宏婚外情的传闻又被提起了。当李靓蕾声称自己曾与BY2有暧昧关系时，这些传言再次浮现。但这些指控最终因缺乏证据而被驳回，当时由BY2提出诉讼反击那些散播这些谣言的人们。

尽管如此，BY2依然在娱乐圈继续前行。他们最新专辑获得了好评，因为粉丝喜欢并欣赏他们独特的声音和风格。不管你是否同意他们改名这个决定，最重要的是，他们仍旧创作出能够触动全世界人们的心灵的音乐。
