（1） Method of suction:

1) Suddenly disrupting the original channel on the technical chart and attempting to break through important technical support levels, triggering stop loss orders from technical speculators, forming a phased bearish trend in stock prices, and then taking the opportunity to buy.

2) Releasing negative news shook investors' confidence, causing them to hand over their chips in panic and take the opportunity to absorb them. Despite the panic, investors turned around and saw that the stock price had not fallen much.

3) Taking advantage of the sluggish market sentiment and quietly buying while suppressing stock prices, although the market seems to have no clear future, individual stock prices cannot fall, only fluctuating narrowly within a certain range, and sometimes even suddenly increasing in volume.

4) The market is approaching the bottom zone, and the main force has to complete the collection task in the short term. Therefore, in the situation where most investors are still uncertain about the overall trend, the main force quickly raises the stock price. The sharp rise in the stock price makes profit seekers eager to sell, achieving the goal of quickly building positions.

（2） The variation pattern of transaction volume during suction:

1) The bottom area of the stock price decline was originally characterized by extreme contraction in trading volume. From one day onwards, there was a moderate increase in volume without attracting attention, and it continued to maintain this level for several consecutive days. The daily trading volume was extremely close, unlike later times when it was large and small. This change was not accidental, but caused by the main force's planned buying.

2) At the bottom of the decline, the trading volume of individual stocks changed from irregular to regular, with a moderate increase in trading volume, while the stock price also slightly rose. This situation reflects the main force's urgent desire to purchase. After the emergence of this trading volume and stock price pattern, a significant rise in stock price is just around the corner.

（3） The K-line shape during the main suction of goods:

1) In the bottom area of individual stock prices, there are repeated cross stars, inverted T-shapes, and T-shapes. These lines continue to appear, and the daily closing prices are roughly the same. The main cost is located between the upper and lower lines or slightly higher. The appearance of these K-lines is a very obvious sign of the main stock's purchase.

2) In the bottom area, it slowly rises with a small bullish candlestick, and the bottom gradually rises. However, these bullish candlesticks have not yet reached a level that is enough to attract people's attention. When the main force pulls up the stock price with a large number of bullish candlesticks, people wake up from a dream.
