Ten Bamboo House stamps were stamps with the painting and calligraphy of Ten Bamboo House as the theme. These stamps were based on Hu Zhengyan's " Ten Bamboo Studio Painting and Calligraphy Manual " of the Ming Dynasty, which showcased the artistic style and techniques of the Ming Dynasty prints. The designs on the stamps included calligraphy, painting, engraving, and many other art forms. Each stamp was accompanied by an inscription and a poem. The Ten Bamboo House stamps had a certain reputation and collection value in the China stamp collection industry.

Ten Bamboo House was the name of the house built by Hu Zhengyan in Nanjing during the Ming Dynasty. He planted a clump of bamboo on one side of his room and named his study "Ten Bamboo House". From then on, he started his publishing career in Ten Bamboo House. The Ten Bamboo House represented the pinnacle of ancient China color engraving printing. It was a symbol of the revival, protection, inheritance, and spread of a legendary traditional China printing technique.
The interior of the bamboo house had a unique layout and structure. Most bamboo buildings had two floors. The upper floor was the living area. From the lower floor to the upper floor, one could enter through nine stairs. The upper level consisted of a front porch, a veranda, and a main room. The front porch was connected to the stairs and was a transition space between indoors and outdoors. It had a roof and no walls. It covered an area of about 20 square meters and had benches that could be used for cooling, resting, housework, storage, and many other functions. The veranda was located at the end of the front porch, south of the bamboo building. There was no roof and it was an open space, similar to a modern balcony. It could be used for washing clothes and drying things. In the early days, when the Dai people were popular with weaving, it could also be used as a matchmaking place. The main room was the main living space. There were two rooms in the room. The inner room was the master bedroom, and the outer room was the central room. In terms of architectural structure, the upper floor was constructed with beams passing through columns. Some beams had exquisite carvings. The beams were erected on the columns in the form of "passing through the bucket". Bamboo boards were laid on the beams to form a two-story space. The walls were surrounded by walls. The walls were inclined outward. The eaves and beams were connected through mortise and tenon joints to support the eaves and increase the space inside the house. In the early days, the Dai people used vines to build bamboo buildings, which had poor stability and needed to be repaired frequently. Later, with the introduction of Han culture, the stability was greatly enhanced after the use of "drilling" and "mortise and tenon" techniques. The lower floor was an empty floor. In the early days, it was completely empty. It was mainly used to store sundries or tie livestock. Now, some new buildings also sealed the lower floor to be used as rooms. The elevated layer could prevent moisture erosion and prevent flooding. It could also be used as storage when it was idle. The interior of the bamboo building was made of bamboo joints, which were used to create fine gaps for ventilation. It could also keep cool in hot and humid weather. With the development of the times, the structure of bamboo buildings had evolved from pure bamboo structures to bamboo and wood structures, brick and wood structures, and reinforced concrete structures in recent years, but the internal layout basically maintained its traditional characteristics.
Bamboo houses were small buildings built with bamboo as the main building material. Most of them were two-story or more bamboo buildings, belonging to the southern "dry column building". Bamboo House had a long history of construction. It was first built in the tropical rainforest of Southeast Asia. In China, bamboo houses were mainly distributed in Yunnan Province, and Xishuangbanna Dai Autonomous Prefecture was the main distribution area. Its construction was affected by the local hot, humid, rainy, lush bamboo and other ecological environments. The structure of the bamboo building had its own characteristics. It was usually made of thick bamboo as the skeleton, bamboo strips as the wall, bamboo strips or wooden boards as the floor, grass as the roof, and 24 main pillars. The entire building had two floors, and the space was tall. The pillars, floors, and walls were made of wood and bamboo, and the roof was covered with thatch and tiles. The upper level was used for living, while the lower level was used for raising livestock and storing farm tools. The roof was wide and flat. Its main function was ventilation, sun protection, and rain protection. The house was hollow, which helped to keep the room dry and cool. It could also avoid the heat, humidity, and insects on the ground. As the symbolic residence of the Dai people, the bamboo house had some special cultural customs. For example, the top beam and the big pillar were called the " falling pillar ". They were the most sacred pillars in the bamboo building. They could not be leaned on or piled up at will. Sometimes, they would be wrapped in red silk to protect the bamboo building from disaster. When people built new buildings, they often put leaves under the pillars. It was said that this would make the house stronger. There were no walls on the ground floor of the bamboo building, which was used to raise livestock and store sundries. There were a central room and a bedroom upstairs. The central room was equipped with a fireplace, which was a place for cooking and family reunion. Outside the upper floor, there was an open front porch and a balcony. The front porch was used for daily work, eating, resting, and receiving guests. The balcony was used for washing, drying clothes, drying crops, and storing water tanks. In addition, in modern times, there were also people who built their own bamboo houses for leisure. For example, someone built his own bamboo house in rural Jiangxi Province, and had his own unique transformation experience in the process of construction and renovation. Bamboo houses were also related to culture and art. There were music composed with bamboo houses as the theme, such as "Love Song of Bamboo House", which showed the sweet love life of young Dai men and women.

Suppose Congcong collected x stamps and Xiaoxiao collected y stamps. According to the conditions in the question, the following two equations can be listed: x + y = 171 (171 stamps collected) x = 4y(1/4 of Congcong's stamps is equal to 1/5 of Xiaoxiao's stamp collection) Substituting x from the first equation into the second equation gives: 4y + y = 171 5y = 171 y = 342 Substituting y = 342 into the first equation gives: x + 342 = 171 x = 1378 Therefore, Congcong collected 1378 stamps and Xiaoxiao collected 342 stamps.
