Wu Tong, a Taiwanese girl with leukemia, came to the capital Beijing to find her father and her twin sister who lost his father more than 20 years ago. And began her wonderful journey across the strait and life and death. Upon arriving at the airport, the young photographer Mu Feng had just returned to Beijing from Yunnan "wandering". He also rushed to the airport to stop his girlfriend's wedding, but he failed to do so. So he took his family's death god and walked to the open bay window of the airport building. The Wutong Wutong Wutong body did not jump down. Instead, he threw a minority folk-style wood carving pendant, which happened to fall at the foot of the Wutong tree. The Wutong tree picked it up, and there was no trace in the person's eyes. He suddenly wanted to take a "backpacker" ride to Yunnan while walking. She informed the backpacker through the bar that Maple Leaf! Mu Feng, who originally thought that love is not free and unimportant, is because his girlfriend does not want to contact women, nor does he want to bring her female travel companion. Who knows that Wutong has a very close relationship with him. I met several times on the road and helped him repair the car and cook. The two quarreled all the way, but different emotions arose. When they arrived in the artistic Lijiang, they were already a pair of intimate lovers. But Wu Tong did not find news of their father and sister. In fact, they don't know that on every street in Lijiang Old Town, they often pass by the new female singer who is filming MTV, and this Xuan is the twin sister of Wutong. The beautiful phoenix trees make a living far from home. Use unscrupulous splitting strategies to surpass others. She even betrayed her boyfriend Lila (Mu Feng's friend), who opened a record company for herself, and signed the famous Star Records. However, Xuanzai is kind by nature. For many years, she has been working hard to cure her adoptive mother's illness and let her younger brother go to school. When Wu Tong was found to be incurable, Mu Feng also hesitated. He is a wanderer of love. Can he afford the responsibility of lying in bed all day? But Wutong was deeply moved by the vigor and kindness of ordinary people and ordinary people. He has no choice. Wutong needed a bone marrow transplant for her relatives. Mu Feng quit her job, slept in the car, and ran around the world to help her find her sister. Wu Tong, the president of the streets and alleys, announced the "no image packaging" publicity plan to make her voice sing the streets and alleys, but her appearance was not shown to the world. Mu Feng found Xuanzi by accident, and never expected that Xuanzi would not be willing to donate bone marrow to her sister! What's the reason for Xuanzi? Wutong has followed his mother for so many years, but was abandoned by his father and has been working hard in the small mountain village. People tried every means to persuade that the mothers of Wutong and Xuanzi were Taiwanese, and even many years ago, the father who had been missing for many years appeared. It turned out that his father was selfish and entrusted Xuanzai to a villager. When he came back, the man was gone. Years of guilt made him ashamed to face his relatives. Even if he becomes the big boss, he will remain anonymous. The family reunited dramatically. After Mu Feng's efforts, Xuanzai finally gave the bone marrow. However, many incidents occurred while waiting for the donation. The brand of Wutong was carved on my heart. The son fell in love with Mu Feng. The disease is rapidly worsening. Xuanzi's younger brother was kidnapped by Wen Bing. This is a song of life, singing the love, affection, friendship and fraternity engraved in the heart.
