近年香港創業潮興起，不少人都想透過「香港店舖頂手」快速入行。但頂手一間店舖絕非簽張合約咁簡單，由睇鋪到接手，處處暗藏殺機。本文揭露頂手老手絕唔會話你知的三大關鍵，等你可以穩陣接盤。
一、頂手前必做三件事
睇清人流真面目
好多「香港店舖頂手」廣告會吹噓「人流爆棚」，但實際要分時段觀察。朝早師奶買餸、後生仔放工、周末家庭客，真正含金量可能得兩三個鐘。
檢查隱形負債
頂手費可能平，但要小心舊租約嘅「魔鬼條款」。曾有案例頂手茶餐廳後，先發現要補交上手欠落嘅冷氣維修費十幾萬。
睇實客戶資產
舊客電話簿、會員積分、WhatsApp訂購群，呢啲先係「香港店舖頂手」最值錢嘅部分。試過有文具店頂手後，新老闆發現上手根本無交收客戶資料。
二、頂手後三大動作
七日換鎖行動
無論幾趕開張，一定要換晒門鎖、收銀系統密碼，連Wi-Fi路由器都要重置。有連鎖超市頂手後無換鎖，結果被前員工返嚟偷貨。
重新計數
上手話月賺八萬？要自己逐項拆解：
燈油火蠟係咪計少咗？
員工強積金有冇扣足？
入貨價同而家市價差幾遠？
快攻街坊口碑
頂手後首個月最好搞「新主理人優惠」，例如：「阿姐退休，新老闆請食糖水」。深水埗有間粥舖就靠呢招，頂手後生意不跌反升。
三、老司機嘅頂手智慧
真正識玩「香港店舖頂手」嘅人，會專搵啲：
老闆年事已高但客源穩定嘅老字號
地點好但裝修過時嘅舖位
有特許經營權但經營不善嘅店
「香港店舖頂手」係門技術活，平買未必著數，貴頂可能更慳成本。記住：頂手唔係接盤，而係用合理價錢買時間、買客源、買地段優勢。睇準先出手，你都可以用頂手跳過創業最痛苦嘅頭半年！
In modern power facilities, communication base stations, and industrial equipment, maintaining proper ventilation while preventing electromagnetic leakage (Electromagnetic leakage) presents a significant engineering challenge. Uncontrolled electromagnetic leakage can interfere with sensitive electronics and potentially compromise data security. This article explores proven methods to minimize electromagnetic leakage through ventilation panels while ensuring adequate airflow.
1. Metal Mesh Shielding
One common approach involves covering ventilation openings with conductive metal mesh. This solution effectively reduces electromagnetic leakage at lower frequencies through reflection and partial absorption. However, its effectiveness diminishes at higher frequencies (above 100MHz), where electromagnetic leakage may still occur.
2. Waveguide Ventilation Panels (Honeycomb Structures)
These specialized panels utilize waveguide cutoff principles to block electromagnetic leakage while permitting air flow. The depth-to-width ratio of the honeycomb cells determines the frequency range where electromagnetic leakage is effectively suppressed, making this solution particularly effective for high-frequency applications.
3. Perforated Metal Plates
Strategically perforated metal sheets offer a balanced solution, providing ventilation while controlling electromagnetic leakage. Smaller perforations and thicker metal provide better shielding, significantly reducing the risk of electromagnetic leakage compared to simple mesh solutions.
4. Conductive Gasket Sealing
Gaps around ventilation panels often contribute to electromagnetic leakage. Conductive gaskets (made of materials like conductive rubber or metal springs) ensure continuous electrical contact at panel edges, effectively sealing potential electromagnetic leakage paths.
5. Multi-Layer Composite Shielding
For critical applications, combining multiple shielding methods (such as metal mesh with waveguide structures and conductive coatings) creates a robust defense against electromagnetic leakage. This comprehensive approach provides superior protection across a wider frequency spectrum.
Controlling electromagnetic leakage through ventilation panels requires careful consideration of frequency requirements, environmental factors, and airflow needs. By implementing appropriate shielding strategies - whether through waveguide structures, conductive sealing, or multi-layer designs - engineers can effectively minimize electromagnetic leakage while maintaining necessary ventilation. Future advancements in materials science may yield even more effective solutions for this persistent engineering challenge.
香港店舖頂手成敗關鍵，往往藏在租約首行「3年死約+3年生約」的小字裡。不少新手老闆誤以為生約期可隨時退場，結果賠上按金又惹上官非。今次就同大家拆解點樣睇穿死約期陷阱，計清免租期著數。
死約期三大伏位
首先要知道，死約期內退租等於自殺。業主有權追討：
餘下租期的全額租金（即使舖位丟空）
沒收相當於三個月租的按金
律師費及追討成本
最近銅鑼灣有茶餐廳頂手，新東主無視尚有8個月死約期，結果被追討廿幾萬租金差額。
免租期殘值計算法
頂手時要將免租期當真金白銀計：
若原租約有2個月免租期，而前手已用1個月
剩餘1個月免租期價值 = 現月租×1
頂手價應相應扣減這筆隱形資產
深水埗有間時裝舖就因計漏免租期殘值，變相多付六萬頂手費。
生約期逃生門
生約期並非自由身，要留意：
多數條款要求提前3-6個月書面通知
退租時須恢復單位原狀（拆裝修要計成本）
業主可能要求新租客接手才放行
佐敦有間藥房就因無預早通知，白交半年租金才甩到手。
記住：死約期剩餘時間越長，頂手價要壓得越低；免租期殘值要當現金扣減；生約期退租條件要白紙黑字寫明。下次見到「香港店舖頂手」廣告，第一時間問業主攞租約副本睇清楚條款，免得接火棒！
