Joyous Wedding is a comedy filled with mistaken identities, misunderstanding and confusion. In the Kingdom of Jin were two princes, one ugly and one handsome. There were also two sisters, the beautiful Hung-luan and the ugly Hung-lin. On one New Year Eve’s night, General Liu Long-ching lost fifty thousand taels of silver which belonged to the public coffer. Unwillingly, he sent his sister, Hung-luan, to Prince Weng for a loan.
It was New Year day, Prince Weng went out to visit friends. When Hung-luan arrived, she met a handsome prince and mistook him as Prince Weng. She begged him to help her brother out. Prince Cen, the handsome one, did not point out her mistake so as not to embarrass her and gave her the loan. He was dazzled by her beautiful face. Hung-luan was moved by “Prince Weng’s” generosity and felt deeply attracted to him.
When he heard of Hung-luan’s beauty, Prince Weng wanted to marry her, so he had it arranged for her to be his bride. Meanwhile, Prince Cen under the name of “Prince Weng” had been seeing Hung-luan, and they were secretly engaged. When the real Prince Weng sent the proposal to marry Hung-luan, she accepted the proposal, thinking that she was marrying her beloved. As if it were not confusing enough, somehow it was arranged for Prince Cen to marry the ugly Hung-lin. It looked like four people’s lives were about to be ruined but just in time Prince Weng realized love could not be forced, so he repented and let Hung-luan marry his brother. And so, Prince Cen and Hung-luan were happily married.
