In China, there are many mega shopping malls. As the malls are very large, there are tons of shops at every level. More than once I would be momentarily separated from my family and would start panicking for fear that I would not be able to find them as I did not have Wi-fi or Google, WhatsApp or Facebook (all banned in China) to help me. Furthermore, many of these shopping malls are filled with small self-owned shops, many of these malls will not bother to create directory maps with store names or shop numbers. Occasionally, one can find sign boards that direct people to amenities such as restrooms, escalators and lifts, it would most likely only be in Chinese or accompanied with broken english.
