1September, 926, Sun Xilin was admitted to Class B of Northeastern University (preparatory class of mining and metallurgy department). With the help of Tong Yuhua (party member) and other students, he joined the Communist Youth League. 1928 On May 3rd, the Japanese imperial government occupied Jinan, causing a sensation in Jinan. Students from the three northeastern provinces joined forces to form a student union to protest against the crime of Japanese imperialism killing China compatriots and launched a patriotic movement to boycott Japanese goods. Sun Xilin organized a sales point to sell domestic products. During the summer vacation at school, he took the poor children near the school to teach literacy. Patriotic students of Northeastern University organized a lecture group, calling on the people of Northeast China to defend their sovereignty and resolutely opposing Japanese imperialism to build the Fifth Road. Sun Xilin, Wu Xiyong and Qiu Huafeng are the backbone of the lecture group. /kloc-in the winter of 0/928, Sun Xilin went to Belgium to study. Although far away from the motherland, he never forgot the motherland and the people for a moment, worrying about national affairs all day. Together with Qiu Huafeng, he initiated and organized the Social Science Research Association to discuss the truth of saving the country. /kloc-in the summer of 0/930, Chinese Communist Party party member Zhu engaged in revolutionary activities in France and was deported. Soon, he joined forces with Belgian progressive students and developed the anti-imperialist grand alliance organization. Sun Xilin and others also participated in the anti-imperialist grand alliance. 193 1 year, Sun Xilin gave up his major in mining and metallurgy and transferred to Leuven University to study law (Leuven University is a missionary school) in order to have more time to engage in revolutionary activities. 193 1 After the September 18th Incident, Sun Xilin and several students in Northeast China were even more heartbroken and indignant after hearing the news that the Japanese army shelled Peking University Camp and occupied Fengtian! More than 200 students from China and overseas Chinese from Belgium gathered in front of the Japanese Embassy in Brussels, Belgium, to protest against Japanese imperialist aggression.

1in the summer of 932, the Belgian authorities arrested overseas Chinese and overseas students, and the anti-imperialist grand alliance was seriously damaged. Members were arrested and detained for one month. Then they announced that Zhu, Sun Xilin, Qiu Huafeng and so on 10 members of the anti-imperialist major league were all deported. Zhu is familiar with the situation in France and has some old relations with Paris, so he decided to take this 10 person to France. As soon as their train entered the French border, it was inspected by the French police. Because they are not allowed to enter the country without passports, Zhu, Sun Xilin and others are in a dilemma and miss their motherland and hometown more, but they are too far away from the motherland. Although they are still childlike, they have no strength to return to the embrace of the motherland. More than 65,438+00 people in this line tried to go deep into France along a small river on the Franco-Belgian border. Until midnight, they bypassed the border checkpoint and boarded the train to Paris. The next morning, they arrived in Paris, the French capital. At that time, they had no source of livelihood and had to turn to the Red Cross for help. The Red Cross agreed to treat them as political exiles and give them a daily living allowance of five francs each. Everyone had to share a room, sleep on the floor and eat only the cheapest chicken rice (broken rice) every day. Sun Xilin works in a rayon factory on the outskirts of Paris. No matter what he does, he finally has a temporary foothold.
