TJGC Group shares surge 21.65% intraday as company expands consulting, international trade via subsidiaries and targets emerging markets like China, Southeast Asia, and the Middle East.

think> Okay, let's tackle this query. The user wants me to transform a given Chinese text into a concise news headline following specific rules. First, I need to make sure I understand all the requirements. The input is about TJGC Group's stock surging during intraday trading by 21.64902005%. The company announced expanding their services through a subsidiary into new markets like China, Southeast Asia, and the Middle East. The key points here are the company name, percentage change (rounded to two decimals), time period (intraday), and the reason for the price movement. First step: Check the company name. It's TJGC Group, so I need to keep that exactly as is. Next, the percentage. The original number is 21.64902005%, which rounds to 21.65%. That's two decimal places. The time period is intraday, so I have to include that in the headline. The reason for the price movement is the expansion into new markets via their subsidiary. The user mentioned to retain key information, so I need to mention the specific regions (China, Southeast Asia, Middle East) and the goals of diversifying the business and enhancing service capabilities. Also, note that this expansion could drive the stock price up. Now, structuring the headline. The example provided starts with the company name, the percentage change, the time period, and then the reason. So following that structure: "TJGC Group surged 21.65% intraday, as the company announced expanding its consulting and international trade services through a subsidiary to enter emerging markets such as China, Southeast Asia, and the Middle East, aiming to diversify its business portfolio and enhance service capabilities, which may drive the stock price upward." Wait, let me check the rounding again. 21.64902005% rounded to two decimals: the third decimal is 9, which rounds up the second decimal from 4 to 5. So 21.65% is correct. Also, the example uses "in premarket trading" for the time period. Here, since it's intraday, I should just say "intraday" without "trading" perhaps? The example uses "in premarket trading", so maybe I should follow that structure. So "in intraday trading". The reason part needs to be concise. The original mentions "通过子公司扩展咨询与国际贸易服务，并计划进入新兴市场..." which translates to expanding via a subsidiary into consulting and international trade services, planning to enter emerging markets. The purpose is to diversify the business portfolio and enhance service capabilities, which could drive the stock price up. So I need to include all these elements in the reason. Putting it all together: "TJGC Group surged 21.65% intraday, as the company announced expanding its consulting and international trade services through a subsidiary to enter emerging markets such as China, Southeast Asia, and the Middle East, aiming to diversify its business portfolio and enhance service capabilities, which may drive the stock price upward." Wait, but the example's output had the company's focus described in a separate sentence. However, the user's rules say to provide a brief reason for the price movement, retaining key info. So maybe I don't need to add more details beyond the reason. The example's output included the company's focus after the initial sentence. But the user's instruction says to "provide a brief reason for the price movement, retaining key information." So perhaps I should keep it in one sentence. Let me check the example again. In the example, the first sentence includes the surge and the reason (the subsidiary's project). Then the second sentence explains more about the company's focus. The user's rules don't mention splitting into multiple sentences but the example does. The rules say "a brief reason for the price movement," so maybe the main reason is in the first part, and the rest can be omitted unless necessary. But in the given example, the output has two sentences. The first is the headline with the surge and the announcement, the second is about the company's focus. The user's rules mention "retaining key information," so perhaps the second sentence is optional but the example includes it. However, the user's instruction says "Please transform the following text according to the above rules," so maybe I should follow the example's structure. Let me check the rules again. The rules state: "Provide a brief reason for the price movement, retaining key information." So the key info is the reason for the price movement. The example's first sentence includes the reason (SunAtion subsidiary's project), and the second sentence gives more background on the company. So perhaps I should structure it similarly: first the surge and the immediate reason, then a brief description of the company's focus if needed. However, in the given input, the company's focus isn't mentioned beyond the expansion plan.
