There are 21 stations on Guangzhou Metro Line 21, which are as follows: Yuancun-Tianhe Park-Tangdong-Huangcun-Daguan South Road-Tianhe Smart City-Shenzhou Road-Science City-Suyuan-Shuixi-Changping-Jinkeng-Zhenlong West-Zhenlong-Zhongxin-Kengbei-Fenggang-Zhucun-Shantian-Zhonggang-Zengcheng Square. A few days ago, the feasibility study report of Metro Line 21 was approved by the province, and the construction can be officially started. The total length of the line is about 60 kilometers, with 20 stations, 6-section B-cars with a top speed of 120 kilometers per hour, and it can operate in fast and slow train mode. It is understood that Line 21 starts from Tianhe Park in Tianhe District, and is laid along Tangde South Road, Daguan Road, Kexue Avenue, Kefeng Road, Shuixi Road and Guangshan Highway, and ends at Zengcheng Square in Zengcheng City. The total length of the line is about 60 kilometers, with 20 stations (including Yuancun Station), including 17 underground stations and 3 elevated stations. According to the current planning, after the completion of Line 21, it can be transferred to several stations, including Yuancun Station and the existing Line 5, Tianhe Park Station and Line 11 and Line 13 Phase II, Huangcun Station and the existing Line 4, Suyuan Station and Line 6 Phase II, Zhenlong Station and Knowledge City Line and Guangzhou-Dongguan-Shenzhen Intercity Line. It is reported that Tianhe Park Station can be interchanged with Line 11 and Line 13 Phase II in the long term. However, due to the complex construction difficulty and long construction period of Line 11, it may not be completed until after Line 21. Coupled with the uncertainty of the construction timing of Line 13 Phase II, Tianhe Park Station, as the starting station of Line 21, cannot be connected with the central city line in the network unless measures are taken. After completion, it can only be interchanged from Huangcun Station and Suyuan Station to the suburban lines of Line 4 and Line 6 Phase II respectively. In order to realize the connection between Zengcheng and Luogang and Guangzhou urban area, make the new line better connect with the already-operated rail transit after opening, and meet the requirement that Zengcheng, East New City and Luogang reach the downtown within one hour, at the construction stage, the Yuancun section of Line 11 will be built simultaneously according to the network planning of the district, thus realizing the connection between Line 21 and Line 5 of the existing downtown area, and facilitating the passengers in Zengcheng area to take Line 21 and directly transfer through Yuancun Station. With the opening of Line 21 subway, the buildings around the subway have become hot, which will naturally attract more and more people to buy houses nearby. The buildings along Line 21 are mainly concentrated in Luogang, Zhongxin Knowledge City, Zhucun and Zhecheng Street, among which the average price of buildings in Zhongxin Knowledge City, Zhucun and Licheng is about 17,000-20,000 yuan/flat. The shipment volume and price increase of Zhucun plate, in terms of second-hand housing, the price of Zhucun plate is around 20,000/flat. Because the new inventory is sufficient and the price difference is not big, it is not recommended to buy the second-hand housing in this plate. If you don&;t sell it, Shenzhen customers may buy it all.
