What super-practical life tips do you have?

These tips or products, I have not used the mobile power supply of Xiaomi 149, the rest are used to feel good use of products and tips to tell everyone.
Go to the pharmacy to buy a bottle of alcohol, usually wipe the keyboard and mouse mobile phone, you can not clean it! (It is best to wipe the screen less when the phone is on, the screen has anti-oil coating).
Go to Ma Yunjia to buy a hot electric, more than 100 singles, usually at home watching TV games, what can be covered, very comfortable, the southern children you will thank me. (Update, the cheap electric heating I bought should be wrapped in a thin quilt on the electric blanket. The working principle is the same as the electric blanket, so be careful to use it, don't touch the water and prohibit folding.)
Mobile power can buy the 129 pieces of Xiaomi's purple rice with fast charge, it seems super thin! Super light! It is about 1mm thicker than most mobile phones, and the weight is less than 200g. The capacity is 10,000 mAh. With the fast charging head, it can charge nearly 80% of electricity in 2 hours. (Update, Xiaomi himself also has a two-way fast charge, qc agreement, 10000 mAh 149 yuan, but more important than the above mentioned)
Daily necessities can be bought on milk tea (only buy self-employed), including but not limited to mops, rags, towels, various sauce seasonings, milk, paper towels (this is too cheap), shower gel shampoo laundry detergent ( Often discounted, full 199-100 or 80, do not think that this kind of activity is a pit, then how is it cheaper than the supermarket, and do not have to take it yourself), sleeve. (When writing this answer, Milk Tea East is still 79, now 99, Ma Yun's supermarket feels OK, it is to buy heavy things will calculate the weight, so the freight may be high.)
