Why did Yan get caught?

Mainly because the situation at that time made Yan unable to resist, he held the clue of the treasure and had enough capital to wait for reinforcements. Yan in the play was given a new identity, and Yan's master changed from an eagle to Zhong Tianxiang. In the setting of characters, Yan's force value is much weaker than other films, and her actions are extremely lacking in thinking, which also leads to Yan being framed and arrested by the Japanese at the end of the play. Flying Eagle on an Island is a spy war drama produced by Wuhan Qingyu Film and Television Culture Co., Ltd., directed by Qian, starring Yuan Ran and others.
