Huhushengwei._splitOtherToken() (#1239-1285) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1267)
Huhushengwei._splitOtherToken() (#1239-1285) ignores return value by doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1278)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Huhushengwei.startTime (#1039) is never initialized. It is used in:
- Huhushengwei.isIn3minter() (#1123-1125)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Huhushengwei._transfer(address,address,uint256) (#1127-1178) performs a multiplication on the result of a division:
-amount = amount.div(100).mul(88) (#1168)
Huhushengwei._splitOtherToken() (#1239-1285) performs a multiplication on the result of a division:
-rate = balanceOf(user).mul(10000).div(totalAmount) (#1265)
-doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1278)
Huhushengwei._splitOtherToken() (#1239-1285) performs a multiplication on the result of a division:
-rate = balanceOf(user).mul(10000).div(totalAmount) (#1265)
-doge.transfer(user,thisAmount.mul(rate).div(10000)) (#1267)
Consider ordering multiplication before division.

Huhushengwei.slitherConstructorVariables() (#1023-1292) uses literals with too many digits:
- _destroyAddress = address(0x000000000000000000000000000000000000dEaD) (#1034)
Use: Ether suffix, Time suffix, or The scientific notation

Huhushengwei._destroyAddress (#1034) is never used in Huhushengwei (#1023-1292)
Remove unused state variables.
