@BillWiIdin I think the restaurant in China is more worth to tip but no need at all. If those American go to dinner in China, they won’t will to tip any more in USA.
@bmay Too much regulations here in Western. Some of them do make sense. Some are annoying. In China it’s like what Nike said “Just do it”. Then they quickly scale up. How can you believe you pay 25 cents to buy a panel per watt in US while Chinese can have the whole solar system?
